July 19, 2024, global tech outage news

Our live coverage of the global tech outage has ended for the day.

Jetstar Japan, Hong Kong Express and Cebu Pacific airlines said Saturday (local time) their operations are gradually being restored after disruptions due to the global tech outage. 

Jetstar Japan said “normal operation is planned” for Saturday with the exception of five flights that were canceled, according to a statement on its website. 

Hong Kong Express said its online booking and check-in systems have “largely resumed” as of Saturday after the service system of its provider Navitaire was impacted by the global tech outage. Four flights will resume Saturday, but 20 remain canceled, the airline said in a statement. 

Cebu Pacific, a Philippine airline, said its automated check-in, booking and other systems “have been restored but flight operations will take some time to normalize due to yesterday’s outage,” according to a statement.

“Our technical teams continue to make positive progress in restoring the full functionality of our systems following the global service outage that is affecting airlines and businesses,” Cebu Pacific’s statement said. 

Only 15 out of 609 experienced minimal disruption Friday in Egypt as a result of the global cyber outage, according to the Egyptian Ministry of Civil Aviation.

Alternative systems were activated to minimize delays and all flights are now operating as scheduled, the ministry reported Friday.

The ministry said it is working closely with GoNow to ensure a full return to normal operations and it has been closely monitoring the situation from the main operations room of the civil aviation ministry, where it is assessing the repercussions of this global crisis and addressing any emerging issues.

The global technical outage affecting various sectors worldwide has resulted in minor impacts on the operational processes of the United Arab Emirates’ airports and airlines, according to the UAE General Civil Aviation Authority (GCAA).

The GCAA reported minor delays in the check-in processes for a limited number of flights. Airlines implemented an alternative system, allowing check-in operations to resume normally.

GCAA added that national carriers are closely monitoring the situation and providing immediate updates and guidance to customers and travelers.

Hertz rental car signage is seen at John F. Kennedy International Airport in Queens, New York City, on March 30, 2022.

The car rental company Hertz saw an influx of customers as a global IT outage continues to impact many airlines and businesses.

Laura Smith, the head of customer experience at Hertz, told CNN Friday that while the company saw no disruptions to IT software, it saw an increase in customers at call centers and physical locations.

Hertz experienced a lot of impact on the East Coast, particularly in Atlanta, Newark, Orlando and Charlotte with one-way reservations.

Smith explained that one customer called who was landing in Atlanta after 8 p.m. and was looking to book a car to drive home to Richmond, Virginia, as their connecting flight was canceled.

On Thursday night and all-day Friday, Hertz brought in extra staff to help with the influx and some employees have worked extra hours as well.

Customers have been generally grateful to the Hertz staff, Smith said, as they realize that renting a car may be the only option for them to arrive sooner to their final destination.

A passenger looks at a flight information board showing multiple delays and some cancellations in flight departures from Dulles International Airport on Friday, July 19, in Dulles, Virginia.

Flight cancellations into or out of the US have topped 3,000 flights as of 8:40 p.m. ET on Friday, according to FlightAware.com.

Over 11,000 U.S. flights were delayed. 

The cancellations come as tech disruptions impact sectors across the globe.

Rob D'Amico, a former FBI supervisory special agent, appears on CNN on Friday, July 19.

A former FBI supervisory special agent said the national security implications of today’s global computer outage are “bigger than most people think.”

Rob D’Amico said that nation-state cyber actors — otherwise known as adversaries with maliciously targeted cyber activity, according to the Cybersecurity and Infrastructure Security Agency — are likely keeping track of what happened during the tech disruption.

He added that another national security issue could be cyber actors potentially taking advantage of the outage by attempting phishing cyberattacks.

CrowdStrike, the company behind the tech disruption, said in a statement Friday that “this was not a cyberattack” and that the company’s team “is fully mobilized to ensure the security and stability of CrowdStrike customers.”

D’Amico said he is skeptical of the firm saying the debacle was not a security incident.

Pedestrians wait in line at the San Ysidro Port of Entry border crossing in Tijuana, Mexico, on Friday, July 19. The US Customs and Border Protection agency said it’s experiencing processing delays due to the global technology outage.

United States Customs and Border Protection is experiencing “processing delays” due to global technical outages that may lead to longer wait times at US ports of entry. 

CBP is working to restore its systems to full capacity and mitigate impacts on its operations as well as on international trade and travel, a spokesperson said Friday. 

Tech disruptions across the world have hit airlines, banks, businesses, schools and governments, along with some health and emergency services. One expert said it could be the “largest IT outage in history.”

Saudi Arabia has seen minimal impact to its critical infrastructure from the global tech disruptions, according to the Saudi National Cybersecurity Authority (NCA).

The NCA is taking proactive measures and monitoring for any further cyber threats, it said in a statement Friday. The agency credited its controls and standards for the minimal impacts seen in the country.

Operations have returned to normal at the country’s King Khalid International Airport in Riyadh, King Abdulaziz International Airport in Jeddah, King Fahd International Airport in Dammam, and Cluster 2 Airports, the Saudi Matarat Holding Company said in a separate statement.

This follows earlier airline disruptions caused by the global technical outage.

Kim Brown was near the end of her shift Thursday night as a labor and delivery nurse at Kaiser Permanente in San Jose, California, when the hospital’s computer systems, which it relies on to care for women in labor and their babies, started getting “a little glitchy.”

Brown says workers there are used to occasional problems like slow-loading medical records, so at first, it didn’t raise any alarms. But shortly after 10 p.m. local time, the computer abruptly shut down. “Oh, that usually doesn’t happen,” the nurse said. When it restarted, it was frozen on a blue screen with an error message.

The scope of the problem revealed itself quickly: It wasn’t just one computer, it was all the computers on the unit.

And it wasn’t just the workstations where they accessed electronic medical records. Something had also taken out a system called FetaLink, which they use to watch the heartbeats of babies in the womb at the nurses’ station. The automated medicine cabinet that dispenses drugs had stopped working. Their security system had coded.

Normally, Brown says, with so many systems down, the hospital would have gone on redirect, a systemwide status that means it can’t take new patients. But when their manager started calling other hospitals nearby, she realized they were all having the same problems.

Kaiser and other hospitals have a backup system called downtime protocols that are implemented if staffers have to work without their computers and track patient care on paper charts.  

They called the hospital’s security guards to sit by the elevators to keep babies safe. Orders for lab tests were faxed or carried to the lab or the pharmacy, which amounted to extra work for nurses and delays for patients who had to wait longer than usual for care.

A group of private sector and government agencies worked overnight to determine the threat and find a solution to the global tech outage, according to the former head of the computer security company McAfee.

Former McAfee CEO Dave DeWalt said the call was set up by CrowdStrike, the company whose update for Microsoft Windows appears to have caused the outages, and that it lasted all night. It included the Cybersecurity and Infrastructure Security Agency and other private and government organizations.

“This particular release was faulty as admitted by George Kurtz, the (CrowdStrike) CEO, and we then had to replace it,” DeWalt said. “But at that point, the damage had been done, and we now had to move into manual mode.”

In manual mode, it takes a village to reboot computer devices and reload operating systems, DeWalt said, adding some of the companies “spent the entire night deploying thousands of people by hand reloading operating systems, starting servers back up again.”

After discovering the problem wasn’t an attack, but rather a conflict with a Microsoft update that occurred earlier, the group had to race against the clock.

A Marriott hotel in Baltimore, Maryland, on Friday, April 12.

The ongoing global IT outage is impacting major hotels, including Marriott International and some Hilton hotels.

Marriott International has nearly 8,900 properties in 141 countries and territories, according to the company’s website.

Impact at other hotels: An assistant manager at the Hilton Phoenix Tapatio Cliffs Resort in Phoenix, Arizona, said they have been having to manually unlock guests’ rooms because the outage impacted the software the hotel uses to make key cards.  

A CNN team saw guests at the hotel using chairs as doorstoppers to keep their doors from closing when they had to leave.

CNN has reached out to Hilton Hotels for comment.

This post has been updated with information from the Hilton Phoenix Tapatio Cliffs Resort.

The global tech outage ricocheted through the brokerage industry, where delays can lead to the loss of money for clients.

A representative from Merrill Edge, owned by Bank of America, told CNN the online trading platform experienced “limited impacts” as a result of the outage. They have since been “largely resolved,” he said.

Charles Schwab also issued a statement on X about ongoing problems. “Due to a third-party, global, industry-wide issue, certain online functionality may be intermittently slow or unavailable. We’re actively monitoring the issue,” a representative for the company wrote.

Cybercriminals are already capitalizing on the chaos from Friday’s massive global tech outage by promoting fake websites filled with malicious software designed to compromise unsuspecting victims, according to warnings from the US government and multiple cybersecurity professionals. 

Hackers have been setting up phony URLs meant to appeal to people seeking information on, or solutions to, the worldwide IT meltdown, but that in reality are designed to harvest visitors’ information or to breach their devices, the security experts said.  

The fraudulent sites use domain names that include keywords such as CrowdStrike — the cybersecurity firm behind a faulty software update that led to the crisis — or “blue screen,” which is what computers affected by the CrowdStrike glitch display when they boot up.  

The fraudulent sites may try to lure victims in by promising a quick fix to the CrowdStrike issue, or scam them with offers of fake cryptocurrency. 

In a bulletin about the outage, the Department of Homeland Security said it has witnessed “threat actors taking advantage of this incident for phishing and other malicious activity.” 

CrowdStrike itself announced on Friday that it has observed hackers “leveraging the event as a lure.”

Malicious actors have created fake websites, sent phishing emails impersonating CrowdStrike employees, and sold fake fixes to address the software bug, CrowdStrike added.

“CrowdStrike Intelligence recommends that organizations ensure they are communicating with CrowdStrike representatives through official channels and they adhere to technical guidance the CrowdStrike support teams have provided,” the company wrote.

The Dow fell 378 points, or 0.9%, on Friday as the tech outage continued to rattle investors. The S&P 500 and the Nasdaq Composite were down 0.7% and 0.8%, respectively.

This has been a destabilizing week for US stocks. It’s just the latest session to see stocks oscillating this week, reaching new highs before swinging back down again.

The S&P 500 posted a new record high on Tuesday. By Thursday, the index had logged its worst two-day decline since April — when Iran launched an attack on Israel. On Wednesday, the Nasdaq had its worst day since 2022.

Investors have struggled to find their footing in recent days as they contend with an assassination attempt on former President Donald Trump, rising odds that President Joe Biden will drop out of the election, attacks on Big Tech and chipmakers from both sides of the aisle and a global computer outage affecting airports, banks, hospitals and other businesses.

The CEO of CrowdStrike promised customers “full transparency” on how the global IT outage involving the company’s software occurred.

George Kurtz said on Friday that CrowdStrike would take steps “to prevent anything like this from happening again,” according to a statement on the company’s website.

“We have mobilized all of CrowdStrike to help you and your teams” to recover from the outage, the embattled CEO told customers.

But that could be easier said than done: Manual restarts of individual systems take time and expertise that some customers don’t have, which is why companies are slow to recover from the outage.

“All of CrowdStrike understands the gravity and impact of the situation,” Kurtz added.

“We are working on a technical update and root cause analysis that we will share with everyone as well,” Kurtz said in a separate post on X Friday afternoon.

Iowa’s critical IT systems have been restored and state services have resumed as normal in the wake of the global outage caused by a software update from CrowdStrike, the state’s governor said.

Iowa uses CrowdStrike software for malware and virus protection.  

Other states and cities also reported disruptions due to the outage.

More effects of the global tech outage are coming to light, as blood centers are altering blood shipment methods and the number of flight cancellations continues to climb.

If you’re just reading in now, here’s what you need to know:

Blood centers affected: Some blood donation centers are changing how they ship blood due to flight delays. New York Blood Center, which supplies about 200 hospitals in the Northeast, initiated an emergency driving operation to distribute collected blood. And Blood Assurance is concerned for its planned shipment of at least 20 platelets — the disc-shaped fragments that help with clotting — due to flight issues.

US flight cancellations: Nearly 9% of all American flights were canceled as of mid-afternoon on Friday, according to Cirium, an aviation analytics company. Even if a plane can take off Friday afternoon, most travelers will not reach their destinations on time. Cirium said 57% of flights in the US have departed with a 30-minute delay or greater.

Drivers’ services: Texas driver’s license offices are closed across the state because of the ongoing outages. The state joins the list of other states who have limited services or closures, including Tennessee, North Carolina and Georgia.

Canadian outages: In British Columbia, the global outage continues to affect the networks and computers of the province’s health system, the Provincial Health Services Authority (PHSA) said. And, the Canada Border Services Agency temporarily experienced a system outage earlier with its telephone reporting system, which is mostly used by small aircraft and boaters.

Nevada gaming: BetMGM, an online sports betting company, said it’s experiencing temporary issues. Las Vegas-based Station Casinos also said its operations have been restored after the outage affected operations. The Nevada Gaming Control Board is monitoring the ongoing situation.

When computers and tech systems around the globe went down Friday, many people had one question: How could this happen in 2024?

A software update from a single cybersecurity company, US-based CrowdStrike, was the root cause of the chaos, underlining the fragility of the global economy and its dependence on computer systems to which relatively few people give a passing thought.

CrowdStrike is everywhere: Numerous Fortune 500 companies use CrowdStrike’s cybersecurity software to detect and block hacking threats. Computers running Microsoft Windows — one of the most popular software programs in the world — crashed because of the faulty way a code update issued by CrowdStrike interacted with Windows.

CrowdStrike, a multibillion-dollar firm, has expanded its footprint around the world in more than a decade of doing business. More businesses and governments are now protected from cyber threats because of this, but the dominance of a handful of firms in the anti-virus and threat-detection marketplace creates its own risks, according to experts.

CNN has requested comment from CrowdStrike.

How to prevent this from reoccurring: The wide swath of critical infrastructure providers affected by the outage is also likely to raise fresh questions among US officials and corporate executives about whether new policy tools are needed to avoid catastrophe in the future.

Anne Neuberger, a senior White House tech and cybersecurity official, spoke of the “risks of consolidation” in the tech supply chain when asked about the outage on Friday.

The CrowdStrike episode “demonstrates the serious damage that could be inflicted by a malicious adversary if they were so minded,” Tobias Feakin, a former ambassador for cybersecurity and critical technology in the Australian foreign ministry, told CNN.

Flight boards show delayed or canceled flights at Minneapolis/St. Paul International airport on Friday, July 19, in Minneapolis.

Nearly 9% of all American flights were canceled as of midafternoon on Friday, according to Cirium, an aviation analytics company.

Cirium reports that, as of 3:30 p.m. ET, 8.9% of all domestic US flights were canceled, or 2,382 total.

Delta had the most flights canceled at 1,176 — or 23.5% of its schedule. United had 515 canceled flights, while American canceled 454 flights.

Even if a plane is able to take off as early as Friday afternoon, most travelers will not reach their destinations on time. Cirium said 57% of flights in the United States have departed with at least a 30-minute delay.

Drivers in multiple states are unable to access all services due to the global IT outage, according to authorities.

Texas: Driver license offices across the state are closed “due to a technical issue” related to the tech outage, which is related to the global CrowdStrike incident,” Texas Department of Public Safety spokesperson Sheridan Nolen said.

Nolen said teams are working to fix the problem, but “there is no current estimate” on when the offices will reopen.

Tennessee: Tennessee’s Driver Services Centers may be unable to process transactions, the Tennessee Department of Safety & Homeland Security said Friday morning.

“The Department of Safety and Homeland Security will provide updates as information becomes available. We apologize for the inconvenience the outage has caused,” the department said. 

North Carolina: The North Carolina Department of Transportation said Friday morning that all NC Department of Motor Vehicles driver license and plate agencies are “unable to assist customers this morning due to the current global Microsoft and CrowdStrike outage.”

NCDOT added that the situation is being monitored “and will resume service once the global outage has been repaired.”

Georgia: The Georgia Department of Driver Services is being impacted as well, according to a post by the agency to social media. 

“Due to the global Microsoft/Crowdstrike outage, DDS services are unavailable at this time,” the post reads.

This post has been updated with information from Texas.

Blood donation centers are experiencing issues with shipments and distribution during the global tech outage.

A planned shipment of at least 20 platelets from Blood Assurance has been postponed due to flight delays and cancellations caused by the outage. 

Platelets are disc-shaped elements within the blood that assist in blood clotting, according to Blood Assurance. Platelets are used for things like bleeding during surgery, cancer treatments and aplastic anemia.

New York Blood Center, a supplier of blood to approximately 200 hospitals in the northeastern United States, has put in place an emergency driving operation to distribute collected blood, Senior Vice President of Corporate Communications and Public Affairs Andrea Cefarelli said.

Blood Centers of America, which relies on shipping companies like FedEx, is sharing a similar experience, as they are also seeing delayed testing results, Executive Vice President Jenny Ficenec said.

Not affected: The American Red Cross has reassured patients and donors that it is not impacted by the outage as it does not use CrowdStrike software, but it is monitoring for any “indirect effects,” according to Nicole Maul, the director of media relations.

OneBlood is also not experiencing issues and is fully operational for blood collections, Senior Vice President of Corporate Communications and Public Relations Susan Forbes said.

After spending more than 19 hours at Atlanta’s Hartsfield-Jackson International Airport, one passenger won’t be getting home to Los Angeles anytime soon.

Hampton described sleeping on the floor at the airport after a previous flight was canceled last night, adding, “It seems like I am going to have to sleep here tonight.”

The Canada Border Services Agency experienced a system outage earlier with its telephone reporting system due to the ongoing global IT outage, but it has since been resolved.

“Earlier today, the Canada Border Services Agency (CBSA) experienced a partial systems outage of its telephone reporting system. This issue is now resolved. Telephone reporting is a system primarily used by small aircraft passengers and boaters,” CBSA spokesperson Jacqueline Roby told CNN.  

Roby said the agency worked “urgently” to mitigate disruptions and to restore services “as quickly as possible.” 

“We are continuing to monitor further potential impacts. No CBSA systems are affected at this time,” Roby added.

In British Columbia, the ongoing global IT outage is impacting the networks and computers of the B.C. health system, the Provincial Health Services Authority (PHSA) said.

According to PHSA, they provide “specialized health care services to communities across British Columbia.”

The impacts of the global tech outage are still being felt across the US, causing anything from city connectivity issues and problems accessing patient records at hospitals.

If you’re just reading in now, here’s what you need to know:

States and cities reporting issues: While there’s been a fix to the issue causing the outage, multiple US cities are still feeling the impacts in a variety of ways.

Hospitals and health systems: While most hospitals remained open to treat medical emergencies, some were not able to access electronic medical records and order lab tests and prescriptions. Those facilities had to cancel patient appointments and surgeries.

Package delays: Shipping companies United Parcel Service (UPS) and FedEx are warning customers there may be some service delays Friday because of the effects of the tech outage.

The global tech disruption is impacting operations at Los Angeles County Superior Court and temporarily limiting inmate bookings in San Diego County, officials said.

“The Court is experiencing significant system-wide connectivity issues that are impacting the Court’s ability to conduct business,” the Los Angeles Superior Court said in an email, adding hearings with parties expecting to appear remotely will be rescheduled.

In San Diego, jail bookings were limited for a few hours while department officials employed back up systems.  

Elsewhere in California, “all 911, public safety communications and critical infrastructure is functioning as expected,” the state Office of Emergency Management said in a social media post.  

“At this time, there are no reports of impacts to life-safety public services in California,” the governor’s office said.

A number of voting locations in central Arizona are impacted by a global power outage that has delayed health care, transport and broadcasting services.

The Maricopa County Elections Department said it is “experiencing an outage at some voting locations,” in a message on its website.

Early voting in the state started on July 3, and Primary Election Day is on July 30. Maricopa County is the country’s fourth-largest county in terms of population, the website said.

The global IT outage that impacted banking and travel on Friday also affected patient care at some hospitals and health systems.

While most hospitals said they remained open to treat medical emergencies, some said an inability to access electronic medical records and efficiently order lab tests and prescription medications had caused them to cancel patient appointments and surgeries.

Here’s what some hospital systems said: 

Large disruptions weren’t universal, however. Other major medical centers — including Johns Hopkins, MD Anderson Cancer Center, Houston Methodist, UC San Diego Health and the Veterans Affairs health system — said they were unaffected by the outages.

Other places, such as Cleveland Clinic and UW Medicine, which is affiliated with the University of Washington, reported that while some of their technology had been impacted by the outage, patient care had not been affected. Memorial Sloan Kettering Cancer Center in New York recently said in an update that its “systems and procedures are now reinstated” after being paused earlier Friday.

A spokesperson for the US Department of Health and Human Services said it is “working to assess the impact of the Crowdstrike outage on patient care and HHS systems, services, and operations,” along with federal, state, local and private sector partners.  

Electronic records systems: Epic Systems, a company that makes widely used electronic health records systems for hospitals and doctors’ offices, said on Friday that its Nebula cloud-based platform had been impacted by a Microsoft outage overnight and that some services, including telehealth visits, were not available during the outage. 

Another electronic medical records company, Veradigm, also said its systems were impacted by the CrowdStrike outage.

Screens display flight information and error messages during a technology outage at the Indira Gandhi International Airport in New Delhi on July 19.

CrowdStrike’s security software is running on countless individual computers all around the globe — which means the update that got pushed to those devices caused them all to shut down, virtually simultaneously.

And in today’s networked economy, an outage in one part of a supply chain can cause domino effects up and down the line. When multiple parts of a supply chain go down, it touches off a cascade of problems.

Some affected machines may be rarely serviced by people or located in remote areas. Others may not even have monitors or keyboards plugged in, because they don’t regularly require humans to directly interact with them.

The most extreme examples may include weather monitoring sensors or devices in railway signal boxes, Andrew Peck, a cybersecurity expert at Loughborough University in the UK, said, which could require technicians to physically visit potentially hundreds of thousands of machines to perform the recovery process.

Portland, Oregon, Mayor Ted Wheeler issued an emergency declaration Friday morning for the city due to the ongoing IT outage, according to a news release.

He said the outage is impacting some city servers and employee computers.

People walk by a digital sign, which normally displays train times, as it shows information about a technology outage in New York on July 19.

The governor of New York described impacts of the global IT outage on transportation links and health care facilities as an “unprecedented situation.”

“Our top priority is emergency services. We are working with localities to ensure that 911 systems are operational,” Gov. Kathy Hochul said. The 911 system is working in all 62 state counties, according to Hochul.

“This has a widespread impact on hospital systems as well,” shared Hochul, adding that “most have backup systems” which are “not technology-based” but rather manned by people.

There is no indication of a cybersecurity threat or risk to personal sensitive information, Hochul said Friday.

A senior White House cyber and tech official spoke to the CEO of CrowdStrike Friday to assess the impact of the global IT outage and confirm it wasn’t caused by a malicious attacker.

Anne Neuberger, who is the deputy national security advisor for cyber and emerging technologies on the National Security Council, said the White House made a flurry of calls today to critical infrastructure firms in the US to get a sense of how disruptive the outage was.

CrowdStrike CEO George Kurtz apologized to customers earlier Friday for a global IT outage caused by the cybersecurity firm’s software update.

Neuberger said at the Aspen Security Forum that she has been involved in inter-agency meetings to assess any impact the outage was having on US government services, 911 systems and other critical functions. She did not offer an assessment of any possible impacts to those systems. 

Shipping companies United Parcel Service (UPS) and FedEx are warning customers they could encounter some service delays due to the global IT outage hitting their systems on Friday.

FedEx said it has instituted its contingency plans to deal with the issues.

This post has been updated with information from FedEx.

Industries from airlines to health care are at a standstill, but one company is taking advantage of the blackout — Krispy Kreme.

The North Carolina-based company is offering a free original glazed doughnut from 5 to 7 p.m. local time on Friday due to the global outage.

Krispy Kreme frequently gives away doughnuts or offers deep discounts to grab attention toward the brand during major holidays or events.

As frustrated passengers line up at airports backed up with flight cancellations and delays, countless businesses and government agencies are waiting for services to get back to normal after a global tech outage.

If you’re just reading in now, here’s what you need to know:

Flight woes grow: Passengers missing life events, like funerals and birthdays, are stuck in a holding pattern as US flight issues continue. More than 2,000 flights have been canceled within, into or outside the US, according to FlightAware. And there are more than 5,300 flight delays as of noon ET. In Latin America, the outages caused delays for some carriers, while airlines in Australia are operating but with some delays.

Resolution will take time: While the company behind the global computer outage has made a fix, the people affected at airports, businesses and government agencies will be feeling its impacts for a while. CrowdStrike’s software runs at such a deep level that getting affected systems and computers up and running poses a huge challenge. Some devices will need a manual rebooting. Read more on the process.

CrowdStrike apologizes: Meanwhile, CrowdStrike CEO George Kurtz apologized to customers Friday for the outage caused by the cybersecurity firm’s software update. He said the company is working with those affected and stressed that this was not caused by a cyberattack.

The number of flights canceled within, into or outside of the United States has climbed to over 2,000, according to FlightAware.

The number of US delays is more than 5,300 as of noon ET.

Delta has canceled at least 640 flights, and Hartsfield-Jackson Atlanta International Airport currently has the most cancellations in the US with 226.

Therapy dogs work at George Bush Intercontinental Airport in Houston on July 19.

Therapy dogs are making the rounds at George Bush Intercontinental Airport in Houston, Texas, as a global IT outage disrupts air travel across the country and the globe.

The dogs, named Clyde and Oliver, are offering support to travelers in the terminals, a spokesperson said. Over 350 flights have been delayed and nearly 100 flights were canceled at the transit hub Friday as of 12 p.m. ET, according to FlightAware.com.

Passengers navigate Hartsfield-Jackson Atlanta International Airport on July 19.

Passengers at Hartsfield-Jackson Atlanta International Airport have had their travel plans upended by delays from the global IT outage, with some unable to get to family emergencies or special occasions.

The New Jersey resident slept at the airport overnight and has had her flight canceled twice. “I want to get home to my son. I want to get home to Jersey,” Small said, adding she doesn’t believe she will be able to travel home until Saturday.

Ty Kelley was traveling to Philadelphia to attend a funeral. “It’s wild, it’s crazy, it’s crowded — I have anxiety right now,” she said. “I’m going to wait in this long line and try and get to Philadelphia today.”

Another passenger told CNN she had been traveling with her toddler to Boston for a birthday party. “It has been frustrating to say the least,” Miya Haney said.

Haney described the manual check-in process her airline, Spirit Airlines, was using. “They’ll send a person going up and down shouting, ‘Boston here, flight number here.’ I have no idea when we are going to get called next and I’m just beyond frustrated.”

Airport officials previously told CNN they expected 300,300 passengers to pass through Hartsfield-Jackson on Friday. The major transport hub leads all airports for canceled flights, with more than 384 eliminated in or out of the Atlanta airport.

Travelers wait in Terminal 1 for check-in at Hamburg Airport in Germany on July 19.

The company behind a massive computer outage across the world says a flawed update has been rolled back — but that doesn’t necessarily help the thousands of businesses that have been affected by the glitch.

Here’s why: The CrowdStrike software issue at the heart of the outage runs at such a deep level in affected computers and systems that getting them up and running just to be fixed will be, in many cases, an enormous challenge.

That’s compounded by the fact that many of the servers that may contain information needed to get these systems working again are themselves caught in a cycle of crashing and rebooting.

The CrowdStrike software at fault operates at what’s called the kernel level of a computer, a much deeper level than what more ordinary applications such as browsers or video games do. This portion of a device has much greater visibility and control over a computer and its components, making it critical for the operation of all other systems — and far more sensitive.

Running at the kernel level means CrowdStrike’s software can do more to detect cyberattacks, but it also means the current bug is causing Windows computers to crash to a “Blue Screen of Death” before users can take any actions to correct it.

Manual rebooting: The issue appears to be recoverable, CrowdStrike has said, but in many cases it requires painstaking work. Each affected device must be accessed by an administrator and manually rebooted into safe mode. Then, the offending CrowdStrike file must be deleted by hand.

For businesses with hundreds or thousands of laptops, desktops and servers running CrowdStrike’s security software, an individual human may have to perform that process over and over and over again.

And organizations that take security seriously will have likely encrypted their computers’ hard drives, making it even more challenging to access the file that needs to be deleted.

After a tech outage spread across the world in the overnight US hours, the effects are still being felt hours later across businesses, airlines and critical services.

If you’re just reading in now, here’s what you need to know:

Airline woes for passengers: Passengers are waiting in long lines from London’s Gatwick Airport to Atlanta’s Hartsfield-Jackson International Airport. Airlines are canceling flights and experiencing delays as the ripples of the outage continue.

So far, more than 1,700 flights into or out of the United States have been canceled as of 11 a.m. Friday, according to FlightAware.com. And, almost 4,500 flights into or out of the US have been delayed. Read more on specific US airports. Airlines across Europe and Asia are also seeing flight disruptions, various carriers said.

911 communications affected: The full reach of the outages is not yet clear nationally, but the Federal Communications Commission said it is still working to assess the impacts. There have been reports of 911 outages in various states, like Alaska, and cities, like Phoenix, where the system was down for hours but has since been restored. Meanwhile, in New York City, 911 services are working.

Public services closures: A number of government services to the public are either closed or facing effects of the outages in parts of the US.

Some states — Tennessee, North Carolina and Georgia – reported they cannot access some of their drivers’ services. And Social Security offices are closed today after the outage shut down some of its services, the agency said, and longer than normal wait times are expected when calling its 800 phone number.

CrowdStrike CEO George Kurtz is pictured in Las Vegas on January 5, 2023.

CrowdStrike CEO George Kurtz apologized to customers Friday for a global IT outage caused by the cybersecurity firm’s software update.

Kurtz reiterated that the outage was not caused by a security breach or a cyberattack, and maintained that CrowdStrike’s customers were “fully protected.” 

An international IT outage has impacted health care, travel and broadcast infrastructure worldwide.

Here are the airports and airlines affected in Latin America:

Officials in New York and New Jersey are still working with local agencies to address the impact of this morning’s global technology outage.

There’s not currently a timeline for the full restoration of services, according to a statement from New York’s chief cyber officer Colin Ahern.

Ahern noted that, while Microsoft says the underlying cause of the issues has been fixed, local governments and service providers are still working through the problems impacting their systems.

Ahern said the state’s priority was to “ensure all 911 systems across New York are operational and able to address emergency response needs.”

In New Jersey, Gov. Phil Murphy has been briefed on the outages and is coordinating with local governments, 911 call centers and utilities to assess the impact on the state and offer assistance, he said in a statement released Friday.

Classes are canceled at all Texas A&M University locations Friday following a global outage involving the cybersecurity firm CrowdStrike, the school said in an alert Friday.

Meanwhile, all campus locations remain open with operations as planned, according to the school.

The university’s main campus is in College Station, Texas, and it has other locations in the state.

Tech disruptions around the world have left flights grounded, businesses struggling with IT issues, and customers unable to access tech services. Here are some companies affected so far:

This post has been updated with additional reporting on the outage and disruptions

A man walks past the London Stock Exchange in 2013.

The London Stock Exchange told CNN that its real-time platforms are back up and running after a four-hour outage caused by “a third-party technical issue.”

The disruption affected the LSE’s news service and FTSE Russell real-time indexes, a spokesperson said.

Meanwhile, Euronext, the pan-European stock exchange, has mostly avoided disruption.

“Trading and market data on Euronext’s exchanges, clearing and post-trade operations are not impacted,” it said.

Earlier in the day, there was an issue affecting several indexes with North American market stocks but it has now been resolved for most of those indexes, the exchange noted.

This post has been updated with additional details on the outage.

Flight information is seen during a technology outage at Detroit Metropolitan Wayne County Airport on July 19.

Flight cancellations into or out of the US have climbed over 1,700 flights as of 11 a.m ET on Friday, according to FlightAware.com.

In addition to the 1,758 flights canceled, 4,473 flights into or out of the US have been delayed today.

Delta tops the list of airlines with 546 cancellations, and Hartsfield-Jackson Atlanta International Airport currently has the most cancellations in the US.

The Federal Communications Commission is still working to assess the reach of communications interruptions associated with the global IT outage, the agency said in a post on X Friday.

There have been reports of 911 outages in different jurisdictions throughout the country.

“We’re working closely with other federal agencies to provide assistance and determine the extent of these service disruptions,” it said.

Passengers traveling through Los Angeles International Airport are experiencing a “mixed bag” of delays and cancellations due to the tech outage, an airport spokesperson told CNN.

Several key airlines at LAX — American, Delta and United — were impacted by the outage. American flights are mostly back online, Delta’s are coming back now, and United’s flights will hopefully follow suit soon, Levine said, in summary.

Levine did not have an estimate on how many passengers were affected and was not aware of any impacts to security or air traffic control.

Here’s what other US airports have told customers this morning.

The Social Security Administration closed its local offices to the public on Friday after a global outage shut down numerous services. The agency said in a statement that it expects longer wait times for the national 800 number, and some online services may be unavailable.

In an internal memo to staff, the agency said employees “should work on internal agency workloads” while they work to restore services.

A notice informs customers that they cannot pay by card during a technology outage at a Waitrose supermarket in London on July 19.

Thousands of companies around the world are struggling with payment processing this morning as a global IT outage brought down systems across a wide range of businesses.

Mastercard and Visa said their payment processing systems are operational.

But here’s why companies are still struggling to accept payments:

Making a digital payment involves “a chain” of computers and, if any one of them is down, the transaction will not complete, according to Andrew Peck, a cyber resilience researcher at Loughborough University in the United Kingdom.

“There are a lot of computers in this chain, and usually the larger the business, the larger the chain.”

Capital Economics, an economic research business, has provided an early assessment of the wider consequences of the disruption.

“While things are still very uncertain, we do not anticipate a major macroeconomic or financial market impact at this stage,” Jennifer McKeown, chief global economist at the consultancy, wrote in a note. 

US markets were lower on Friday morning after a global computer outage hurt tech stocks, which were already experiencing a steep drop this week.

The open also follows a report that said the Biden administration is considering heightening semiconductor trade restrictions between the US and China.

This week has been a volatile one for stocks: The S&P 500 posted a new record high on Tuesday. By Thursday, the index had logged its worst two-day decline since April.

The Dow was 214 points, or 0.5% lower. The S&P 500 was down 0.1%. The Nasdaq Composite lost 0.2%.

The city of Philadelphia says it has been impacted by the international IT issue, but its “911 and life and public safety systems remain functional.”

“City staff and employees are to still report to work to assist with critical support tasks related to the outage,” according to a statement. 

Meanwhile, traveler William Sikora, who is at Philadelphia International Airport and trying to fly home to Los Angeles today, told CNN it’s “only getting crazier here now.”

Sikora added that as people sit near their gates, it’s getting “really hot in here; not fun.”

He was originally scheduled for a 6 a.m. ET flight on Delta. He now says the airline keeps pushing flight times back.

As of 9:55 a.m. ET, there have been more than 1,384 cancellations into or out of the US, including at least 39 cancellations at Philadelphia International Airport, according to flight-tracking software FlightAware.

The global cyber outage that caused disruptions to airlines, businesses and emergency services on Friday could be the “largest IT outage in history,” according to cybersecurity expert Troy Hunt.

“I don’t think it’s too early to call it: this will be the largest IT outage in history,” Hunt said in a post on X on Friday.

Other recent large outages:

US President Joe Biden has been briefed on the outage and his team is in touch with CrowdStrike and impacted entities, according to a White House official.

The president’s team is also engaged with agencies “to get sector by sector updates throughout the day and is standing by to provide assistance as needed,” according to the official.

Biden remains at his residence in Rehoboth Beach, Delaware, where he’s self-isolating after testing positive for Covid-19.

The Phoenix Police Department’s 911 call center is now operational and “systems have been restored” following a widespread outage that began last night, the department said in an update on X Friday.

“If you called for non-emergency police assistance during the outage, please be patient as we work through those calls,” the update said.

Global outages “could be causing delays” in some LATAM Airlines flights, the Chilean carrier announced on Friday.

Passengers should “preventively” check their flight status ahead of any scheduled departures, LATAM said in a post on X.

Panama-based Copa Airlines also said some flights might be delayed in an X post on Friday. 

The airline asked passengers to “go to the airport at least 4 hours before your departure.”

The US Department of Homeland Security says it is “working with CrowdStrike, Microsoft and our federal, state, local and critical infrastructure partners to fully assess and address system outages” in a statement on X.

The global IT outage has affected major services worldwide and has particularly disrupted flight operations at major airports.

Here’s what some airports across the US are telling their customers at the moment as flight delays and cancellations contiue:

Hartsfield-Jackson Atlanta International Airport: Airside operations are working, although some customer-facing airlines “are dealing with a few challenges,” amid the ongoing global computer outage, Andrew Gobeil, who oversees public affairs outreach at the airport, told CNN.

“We know that this is uncomfortable. It’s Atlanta, it’s the summer. It is hot, it is humid. People are a little on edge,” Gobeil said. “Have patience. We’re trying to have grace and patience with all of the passengers. We’re asking the same. If there are challenges that are impacted, if people are going to be delayed and have to spend an extra amount of time here at Hartsfield Jackson – work with the airlines, work with our customer service representatives.”

Dallas Fort Worth International Airport: “Due to the global technology issues impacting multiple airlines, we anticipate significant delays and cancellations throughout the day,” the airport said. “We ask customers to verify your flight status with your airline prior to heading to the airport. Longer lines are possible so allow extra time.”

Chicago O’Hare International Airport: The airport advised passengers to check their flight status directly with their carrier due to the tech issues. “Longer lines and wait times are possible, please allow extra time,” it said.

John F. Kennedy International Airport: “The Port Authority is not affected by the ongoing global network outage, but some airlines are experiencing delays/cancellations. DO NOT head to the airport unless your flight status is confirmed,” the New York airport said.

Charlotte Douglas International Airport: The airport advised passengers not to come to the airport “unless they have confirmed their flight information with the airline.”

Miami International Airport: Officials advised that US Customs and Border Patrol operations are being affected nationwide, “so international passenger arrivals are currently being processed manually at a slower pace.”

People are seen at Hartsfield-Jackson Atlanta International Airport during a technology outage on July 19.

As many as 300,000 passengers will travel through Hartfield Jackson International Airport on Friday, according to a spokesperson, as an IT outage causes delays in the world’s busiest flight hub.

At least 104,000 travelers are being screened through security, Gobiel added. He asked passengers to have “grace and patience” with the airlines, adding that they are their “most important partners,” in addition to carriers and law enforcement.  

Over 3,500 cameras are spread across the airport, according to Gobeil, who says they are well prepared for “monitoring everything.” Airport operations teams and customer service members have been deployed to crowded areas to answer customers’ questions, he added.

The US Department of Justice is experiencing some impacts from the technology outage caused by CrowdStrike, according to an internal memo viewed by CNN.

The memo says the department is searching for workarounds but warns staff that the CrowdStrike issue “is significant and there is currently no estimated restoration time.” 

While communications are not impacted on phones and tablets, some applications used by the department, like Microsoft Office programs, may not be accessible to users, according to the memo.

The Justice Department “alerted users this morning that DOJ is among businesses and government users worldwide affected,” according to the statement.

Passengers stand in line at a Delta Air Lines counter at Haneda Airport in Tokyo on July 19.

Delta Air Lines has resumed some flight departures after the global tech outage impacted airlines and businesses around the world, the airline reported Friday morning.

Delta has issued a travel waiver for all customers who have booked flights departing today, according to an 8 a.m. ET update from the airline. As part of the waiver, fare differences will be waived when rebooking travel on or before July 24 in the same cabin of service.

Additional delays and cancellations are expected Friday, and customers are asked to monitor and manage their itineraries on Delta.com or their airline’s app.

Earlier today, Delta said it has “paused its global flight schedule” due to the IT outage.

Transport infrastructure across Italy, including trains, airports and highways, have been impacted by a sweeping outage.

In the Italian city of Genoa, long haul semi-trucks waiting to offload cargo at the Port of Pra were lined up nearly 20 kilometers (about 12 miles), the port authority said Friday. The tech outage caused the automated gate system to malfunction.

Further north, in Florence, Italy’s Trenitalia and Italo train networks were also suspended after systems went offline, the Transport ministry said. Passengers called emergency services and demanded to be let off the trains because of extreme heat, after enduring delays up to 140 minutes. Trains on rural rail lines have been stopped due to extreme heat.

Milan’s FTSE MIB stock market confirmed that it is unable to update figures. 

Elsewhere, Italy’s major airports in Rome, Bologna, Milan and Palermo did not report infrastructure problems, but are experiencing major delays caused by other issues impacting takeoff and landing schedules. 

Italy’s autostrada highway service ‘Autogrill’ also experienced malfunctions but were able to switch to manual systems for petrol and other services. 

The country’s highway toll system also experienced delays with automated Telepass lanes, which utilize card readers tied to an international network.

Mass tech outages worldwide have caused IT systems to shut down, sparking delays and issues at European airports as well as affecting other transport links.

Here are the affected airports and airlines in Europe:

Tech outages scrambled operations across the world Friday, and airports bore the brunt of that struggle.

From Manila to Berlin to Newark, pilots, crew members and passengers were left stranded at airports as the outages caused major delays and cancellations.

Here’s what the scene looks like at airports across the globe:

Long lines of passengers form at the check-in counters at Ninoy Aquino International Airport in Manila.

People wait for their flights at Brandenburg Airport in Berlin.

Crowds are seen building up at Suvarnabhumi Airport in Bangkok.

United Airlines employees wait by a departures monitor displaying a blue error screen, also known as the "Blue Screen of Death" at Newark International Airport in New Jersey.

Passengers line up at Madrid-Barajas airport in Madrid.

The United Arab Emirates Ministry of Foreign Affairs has restored its electronic systems to normal following a global tech outage, the ministry said Friday.

The ministry said attestation services would also continue.

A major East Coast airport has urged passengers not to come to the airport “unless they have confirmed their flight information with the airline.” 

Charlotte Douglas International Airport is one of nine nationwide American Airlines hubs.

At Miami International Airport, another American Airlines hub, officials say US Customs and Border Patrol operations are being affected nationwide, “so international passenger arrivals are currently being processed manually at a slower pace.”

Public transport in New York City, including bus and train services, are not affected by the outage, according to the local transit authority.

However, countdown clocks in stations are not working and customers may find that some functions in apps are unavailable, the city’s Metropolitan Transit Authority said.

The MTA oversees the New York City’s subway and bus systems; the Long Island Railroad, which services Long Island; and the Metro-North Railroad, which services Connecticut and upper New York.

At airports across the globe, airline staff are scrambling to reassure customers and try to provide some clarity on when – or if – their flight might finally be able to take off. Some are resorting to paper-based systems to try to speed up the process while the IT system is down.

While staff might be able to console customers, they can do little until the computer systems are fully operational again, said Mary Schiavo, a CNN aviation analyst and former Inspector General at the US Department of Transportation.

“The lines at certain airports are literally out the door. So it’s having a pretty big impact. People are clinging to hope that the fix for the computer problem has been put in place,” Schiavo told CNN.

But she said “you cannot fly” without a fully operational IT system. “Other than putting a bag tag on, it’s all computer,” she said.

The global computer outage affecting airports, banks and other businesses on Friday appears to stem at least partly from a software update issued by major US cybersecurity firm CrowdStrike, experts told CNN.

CrowdStrike told customers early Friday that the outages were caused by “a defect found in a single content update” of its software on Microsoft Windows operating systems, according to a post on X from CEO George Kurtz.

CrowdStrike’s cybersecurity software — used by numerous Fortune 500 companies, including major global banks, health care and energy companies — detects and blocks hacking threats.

The company said the outage was not caused by a security incident or a cyberattack. Kurtz, in his post, said the issue was identified and isolated, and engineers deployed an update to fix the problem.

CrowdStrike’s (CRWD) stock fell 10% in premarket trading.

The president and CEO of CrowdStrike, George Kurtz, has apologized for the impact of worldwide outages caused by a software update issued by the company, which has disrupted critical health care, travel and broadcasting services.

Speaking on NBC’s Today, Kurtz said: “We’re resolving, and have resolved the issue now.

“As systems come back online, as they’re rebooted, they’re coming up and they’re working,” he added. “And now we are working with each and every customer, to make sure that we can bring them back online.”

A Microsoft operating system had been impacted by the update, Kurtz clarified, saying that his company would have to further investigate “the way some of these operating systems work.”

“And as you might imagine, we’ve been on with our customers all night and working with them. Many of the customers are rebooting the system, and it’s coming up and it’ll be operational because we fixed it on our end, and some of the systems that aren’t recovering, we’re working with them,” he told NBC.

“It is our mission, it’s why we’re here, to make sure that every customer is fully recovered, and we’re not going to relent until we get every customer back to where they were. And we continue to protect them and keep the bad guys out of their systems,” he added.

A global IT outage has swept major services worldwide, disrupting public transport links, delaying international flights and restricting operations for health care facilities and businesses.

Here’s what you need to know:

What is behind the outage? The outage appears to stem at least partly from a software update issued by Crowdstrike, on Microsoft Windows systems. The US cybersecurity firm told customers early Friday that engineers were addressing the problem, according to an advisory viewed by CNN. The issue is specific to Falcon, which is designed to protect files saved in the cloud.

How long will the outage last? Microsoft said the “underlying cause” of the outage “has been fixed,” adding that residual impact is still affecting some services. “We’re conducting additional mitigations to provide relief,” the tech company said in a post on X. Some services have been restored, but others are still grappling with the disruptions.

Who has been affected? Global banks, medical services and critical infrastructure have been impacted by the outage. Medical providers including the UK’s National Health Service, and one of Europe’s largest health facilities in northern Germany, have been stifled by IT delays. Meanwhile, banks, broadcasting outlets and supermarkets in Australia, New Zealand and the UK were affected, including ABC News and Sky News.

Airlines worst hit: Scenes emerged of flustered travelers filling the corridors of major airports on Friday, as US and other international carriers in Europe, Asia and the Middle East had to delay and cancel flights. There are around 110,000 scheduled commercial flights today worldwide, according to preliminary data from Cirium, an aviation analytics company, shared with CNN. As of 6 a.m. ET, there were 1,390 canceled flights globally. That figure is growing.

International response: The White House says it is “looking into” the disruption caused by Friday morning’s cyber outages. “We’re aware of the incident and are looking into the issue and impacts,” a White House National Security Council spokesperson told CNN. Meanwhile, the UK government held an emergency meeting to discuss the outage, Downing Street said, according to the UK’s PA Media news agency. 

The UK government held an emergency COBR meeting to discuss the global tech outage, Downing Street said Friday, according to PA media. 

The spokesperson added that she is not aware of any government business being hit by the outage.

Asked why British Prime Minister Keir Starmer did not chair the meeting of the committee, the spokesperson said the Prime Minister “has had bilaterals with President Zelensky and Cabinet this morning, but all ministers including the Prime Minister are being kept informed with the latest.”

Cabinet Office Briefing Room (COBR) meetings bring together a committee of government department representatives to discuss the nation’s emergency response to crises.  

The White House is “looking into” the disruption caused by Friday morning’s cyber outage that has hit airlines and businesses around the world.

The outage appears to stem at least partly from a software update issued by firm CrowdStrike, experts tell CNN. The CEO of CrowdStrike said that the IT issue causing a global outage has been identified and that a fix has been deployed.

There are no indications at this time of malicious activity, though the administration is still investigating, according to a source familiar.

Delta Air Lines says it has “paused its global flight schedule” due to the IT outage that has hit airlines and businesses worldwide.

The airline says it intends to issue new travel waivers for impacted customers.

Emergency communication services were down in several states on Friday morning following a global IT outage affecting airports, banks and other businesses.

Police in Phoenix, Arizona, said the outage had impacted the Phoenix Police Department’s computerized 911 dispatch center, but the 911 center remained operational.

“If you need to call 911, stay on the line if you are put on a brief hold. City IT is working diligently to find a workaround until the outage has been restored,” police said on X.

In Alaska, many 911 and non-emergency call centers aren’t working correctly across the state, Alaska State Troopers said in a Facebook post. 

In New Hampshire, some 911 services were down overnight across the state but have since been restored, New Hampshire 911 said. 

Meanwhile, the New York City mayor’s press secretary said critical infrastructure and emergency operations, including the 911 call system, have not been impacted.

Fabien Levy, deputy mayor for communication for mayor Eric Adams, told CNN that, since the outage impacts Windows-based devices receiving automatic updates, the NYC Office of Technology and Innovation has been working the past few hours to halt any forthcoming updates and minimize potential disruptions.

CNN has reached out to the Federal Communications Commission for more information on nationwide 911 outages.

The failure of IT systems across the world have caused delays and issues at airports across Asia, causing several airlines to ground flights.

Here’s a look at how the outage is affecting airports and airlines in Asia:

Microsoft said the “underlying cause” that caused the global outage “has been fixed,” adding that residual impact is still affecting some services.

“We’re conducting additional mitigations to provide relief,” the post added.

More on what’s behind this: The outage appears to stem at least partly from a software update issued by firm CrowdStrike, experts tell CNN. The CEO of CrowdStrike said that the IT issue causing a global outage has been identified and that a fix has been deployed.

Poland’s largest container terminal, Baltic Hub, has restored its operations after being hit by the tech outage earlier on Friday. 

Earlier Friday, Baltic Hub said on its website it was “struggling” with “a global Microsoft operating systems failure,” which was “hampering the terminal’s operation.”  

Baltic Hub is Poland’s “largest and fastest growing container facility, and the only deep-water terminal in the Baltic Sea Region,” according to the its website.

William Sikora III tells CNN that the current situation at Philadelphia International Airport is “absolutely insane right now” as passengers are impacted by a tech outage affecting flights around the world.

Sikora was attempting to fly back home Friday morning to Los Angeles and said the outage is already ruining his day with lines moving nowhere as he and thousands others at the airport wait for answers.

A screengrab from a video taken by William Sikora III shows travelers at the Philadelphia International Airport on Friday morning.

He said even if flights are just delayed, he expects many delays are going to eventually become canceled flights.

And if they don’t, Sikora said he will have to have family drive nearly an hour to come get him at the airport.

Public transport including trains and buses in Washington, D.C. have been impacted by Friday’s outages, the US capital’s transit authority has said.

The website for the Washington Metropolitan Area Transit Authority (WMATA), and a number of internal systems are “currently down,” according to a post on X, which said: “Our IT teams are working to address this issue.”

Trains would be held up from their normal 5 a.m. start time, WMATA added, also citing potential bus delays. The MetroAccess call center is down and anyone with a reservation will be contacted if their trip is canceled, the public transportation authority reported.

The Federal Aviation Administration (FAA) is “closely monitoring” the cyber outage Friday morning that has hit airlines and businesses globally.

Major US carriers, including Delta, United and American Airlines, have had flights grounded, according to the FAA. International airlines, including Virgin Australia and Qantas, have also seen disruptions.

The CEO of CrowdStrike, a cybersecurity firm that has Microsoft among its clients, says the IT issue causing a global outage has been identified and that a fix has been deployed.

CNN has also reached out to the White House about the outages.

One of Europe’s largest medical care facilities, located in Germany, has been implicated by the cyber outage.

The German University Medical Center Schleswig-Holstein (UKSH) canceled all elective procedures on Friday, according to a statement on its website.

Both locations in the cities of Kiel and Lübeck, northern Germany, have been affected. Outpatient clinics are also closed.

The “care of patients at the UKSH is secured, as is emergency care,” the statement added. 

The CEO of cybersecurity firm CrowdStrike said a fix for the global tech outage was on the way — but until the issues are resolved, they’re causing chaos at airports across the globe.

Cirium, an aviation analytics company, shared preliminary data with CNN on Friday about the extent of the disruption.

The Delta ticket counter is backed up at the Milwaukee Mitchell International Airport during a global ground stop on Friday, July 19.

A global tech outage has caused delays and issues with airlines across North America.

Here’s the latest on what we know so far:

Dubai International Airport, one of the world’s busiest aviation hubs, resumed its normal operations following global IT outages, the airport announced on Friday.

Government affected: But the United Arab Emirates Ministry of Foreign Affairs said on Friday that a global technical issue has affected some of its electronic systems, including its attestation service.

“We advise all clients to refrain from conducting any transactions until this issue is resolved,” the ministry said in a post on X.

George Kurtz, co-founder and chief executive officer of Crowdstrike Holdings Inc., is interviewed at the RSA Conference in San Francisco, California, US, on April 26, 2023.

CrowdStrike CEO George Kurtz said that the IT issue causing a global outage has been identified and that a fix has been deployed.

Kurtz said the cybersecurity company is working with “customers impacted by a defect found in a single content update for Windows hosts” and that the issue was “not a security incident or cyberattack.”

Here’s his full statement:

CrowdStrike logo of an US cybersecurity technology company is seen on a smartphone and a screen on March 15, 2021.

The global computer outage affecting airports, banks and other businesses on Friday appears to stem at least partly from a software update issued by firm CrowdStrike, experts told CNN. 

CrowdStrike told customers early Friday that it was “aware of reports of crashes” of its software on Microsoft Windows operating systems, according to a company advisory viewed by CNN.

The company’s engineers took action to address the problem, according to the advisory, which told customers to reboot their computers and perform other actions if they were still having technical issues. The issue is specific to Falcon, one of CrowdStrike’s main software products, and is not impacting Mac or Linux operating systems, according to the advisory.

CrowdStrike’s cybersecurity software — used by numerous Fortune 500 companies — detects and blocks hacking threats. Like other cybersecurity products, the software requires deep-level access to a computer’s operating system to scan for those threats. In this case, computers running Microsoft Windows appear to be crashing because of the faulty way a software code update issued by CrowdStrike is interacting with the Windows system.

CrowdStrike is perhaps best known for investigating the Russian hack of Democratic National Committee computers during the 2016 US election. But the multibillion-dollar firm does business around the world through software sales and investigations of major hacks.

CNN has requested comment from CrowdStrike.

American Airlines has resolved a technical issue that impacted their services Friday morning, the airline said. 

“Earlier this morning, a technical issue with a vendor impacted multiple carriers, including American. As of 5 a.m. ET, we have been able to safely re-establish our operation. We apologize to our customers for the inconvenience,” the airline said in a statement to CNN.

The UK’s National Health Service (NHS) said the IT outages have affected most GP practices in England, but there is no known impact on emergency services.

“The NHS is aware of a global IT outage and an issue with a GP appointment and patient record system,” NHS England said Friday.

It said it has “long standing measures in place to manage the disruption, including using paper patient records.”

NHS England encouraged people to use emergency services “as they usually would.”

The global tech outage has caused some Metropolitan Transportation Authority (MTA) customer information systems to go temporarily offline Friday morning, according to officials. 

“Train and bus service is unaffected,” the MTA said in a post. “Please listen for announcements in your station, on your train, or on your bus.”

The MTA is North America’s largest transportation network, according to its website, and serves a population of 15.3 million people.

India’s Ministry of Electronics and Information Technology said the reason for the ongoing tech outage has been identified and “updates have been released to resolve the issue.”

The ministry “is in touch with Microsoft and its associates regarding the global tech outage,” Ashwini Vaishnaw, India’s minister for railways, information and broadcasting, electronics & information technology, said via X on Friday.

The Jaipur International Airport in the western Indian state of Rajasthan said earlier that “flights nationwide ” have been affected by the outage.

Chhatrapati Shivaji Maharaj International Airport in the financial capital of Mumbai also shared an advisory via X, saying “select airline operations” were affected, including “booking, check-in, access to boarding passes and flights.”

Delhi’s Indira Gandhi International Airport and six Indian airlines have also reported technical difficulties, resulting in the disruption of their services.

Budget airlines at South Korea’s Incheon International Airport are experiencing delays in check-in and boarding procedures due to internal system failures, an airport spokesperson said.

Air Premia, Jeju Air, Eastar Jet, Jetstar and Hong Kong Express airlines are experiencing delays in issuing boarding passes at check-in counters and during boarding procedures, the spokesperson said. 

The airlines use computer systems based on Microsoft’s cloud service. Incheon International Airport does not use the Microsoft system, and so is not experiencing any disruptions, its spokesperson told CNN.

The South Korean flag carrier Korean Air said it uses Amazon Web Services (AWS) and was not affected by the outage.

CrowdStrike stock plummeted by more than 18% in pre-market trading on Friday in New York, indicating heavy selling pressure that could cause it to open sharply lower.

Microsoft’s shares also declined 2%. Both companies are listed on the Nasdaq exchange.

Industry experts have said the global tech outages appear to stem from an issue with CrowdStrike, a cybersecurity firm that has Microsoft Windows among its clients.

Pete Buttigieg, US Secretary of Transportation, speaks during a news conference in Long Beach, California, on July 18.

US Transportation Secretary Pete Buttigieg said the government was monitoring technical issues at Frontier Airlines, which had to ground all flights after citing problems involving a Microsoft outage.

Earlier on Thursday, Frontier said its systems had been “impacted by a Microsoft outage, which is also affecting other companies.”

The Federal Aviation Administration said Frontier asked it to pause the airline’s departures across the US, though that ground stop was lifted later that night.
