Thousands of US flights were grounded Friday as a technical disasterplagued government agencies andbusinesses worldwide– leading to countless stranded passengers, canceled medical procedures anddisrupted 911 services.

A cybersecurity company said the debacle is “not a security incident or cyberattack.” But the technical fiasco has paralyzed airlines, banks, state agencies and even emergency services around the world.

As of Friday evening, more than 3,000 flights into, out of or within the United States had been canceled and more than 11,000 delayed, according to FlightAware.com.

Charlotte Douglas International Airport in North Carolina told passengers not to come to the airport unless they had confirmed their flights. Bewildered travelers at the world’s busiest airport in Atlanta were stranded as they tried to get to urgent events.

“Tomorrow, I have a funeral in the afternoon,” said Ty Kelley, who was stuck at Hartsfield-Jackson Atlanta International Airport – which had the most cancellations Friday morning.

“And then on Sunday, I have my sister’s 50th birthday party,” Kelley said. But it’s not clear when or if she’ll make it to those events: “It’s really chaotic. It’s frustrating. And I’ve never experienced anything like this.”

Live updates: Global tech outages hit airlines, banks and businesses

The Federal Aviation Administration “is closely monitoring a technical issue impacting IT systems at U.S. airlines,” the agency posted on social media. “Several airlines have requested FAA assistance with ground stops until the issue is resolved.”

CrowdStrike, a cybersecurity firm that has Microsoft among its clients, “is actively working with customers impacted by a defect found in a single content update for Windows hosts,” CEO George Kurtz posted on X. “This is not asecurityincident orcyberattack.”

Kurtz promised customers “full transparency” on how the outage occurred. He said CrowdStrike would take steps “to prevent anything like this from happening again,” according to a statement on CrowdStrike’s website.

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

Former McAfee CEO Dave DeWalt told CNN that a group of private sector and government agencies worked overnight to “ascertain the threat” and find a solution to the global outage.He said he was on the call, which included the Cybersecurity and Infrastructure Security Agency and other private and government organizations.

Microsoft released a statement midday explaining the situation.

“Yesterday, CrowdStrike released an update that began impacting IT systems globally,” Microsoft CEO Satya Nadella posted on X. “We are aware of this issue and are working closely with CrowdStrike and across the industry to provide customers technical guidance and support to safely bring their systems back online.”

What US airlines are saying

Delta Air Lines “paused its global flight schedule this morning due to a vendor technology issue that is impacting several airlines and businesses around the world,” it said in a statement Friday morning. Delta later said it was resuming some flights. The airline apologized to impacted customers and said a travel waiver would be issued.

JetBlue operations “remain normal and we are not experiencing any system-wide delays or cancelations,” the airline said in an email to CNN. However, “Customers should monitor their flight status and build in extra time in the event that this outage has impacted specific airports due to outages at other airlines, airport operators, or government agencies.”

American Airlines said it has resolved the issue affecting its operations. “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,” American said in a statement. “We apologize to our customers for the inconvenience.”

– Numerous international airlines reported technical disruptions, including Virgin Australia and Qantas, along with airports across Europe and Asia-Pacific.

Federal services and health care are stymied

The calamity also struck hospitals and federal agencies, forcing each to scramble for solutions.

“Many of our Microsoft-based computer systems have been affected by the worldwide technology outage,” Cincinnati Children’s hospital posted on X. “Our teams are working hard to minimize disruption to patient care and system operations, and we are bringing systems back up as quickly as possible.”

At Harris Health System in Houston, “elective hospital procedures are being canceled today and will be rescheduled when the information systems issues are resolved.”

At Mass General Brigham in Boston, “all previously scheduled non-urgent surgeries, procedures, and medical visits are cancelled today,” the health care system told CNN in a statement.

“Mass General Brigham remains open to provide care to patients with urgent health concerns in our clinics and emergency departments, and we continue to care for all patients currently receiving care in our hospitals.”

And in Canada’s British Columbia, the Provincial Health Services Authority announced the health system was affected by the IT outage. “We have implemented contingency plans to ensure that our health care services remain operational, and that patient care is not disrupted to the best of our ability,” said the organization.

In addition to hospitals, blood donation centers have experienced challenges due to flight cancellations and delays. One center, Blood Assurance, told CNN that a planned shipment was postponed due to flight delays and cancellations.

“We are asking community members to help through donation,” Blood Assurance said in an email. “We have a fantastic community of donors that always shows up when we need them.”

Elsewhere, New York Blood Center, a supplier of blood to approximately 200 hospitals in the Northeast, has put in place an emergency driving operation to distribute collected blood, said Andrea Cefarelli, the senior vice president of New York Blood Center Enterprises.

Test tubes of blood sent to be tested before they’re distributed “are not making it onto planes from yesterday and today, requiring for us to drive them,” Cefarelli told CNN in a phone call. “There is going to be a 12-24 hour delay in getting the test results.”

The American Red Cross has reassured patients and donors that they are not impacted by the global IT outage as they do not use CrowdStrike software.

The US Department of Justice was searching for workarounds Friday, according to an internal memo viewed by CNN. The memo said the CrowdStrike issue “is significant and there is currently no estimated restoration time.”

And due to the Microsoft and CrowdStrike debacle, “local Social Security offices are closed to the public today,” the Social Security Administration’s website said.
