The outages appeared to be linked to an update from cybersecurity firm Crowdstrike, which is used by over half of Fortune 500 companies, the U.S. firm said in a promotional video this year.
In a post on X, CrowdStrike CEO George Kurtz said the outage was not a "security incident or cyberattack."
He said it was connected to a "defect found in a single content update for Windows hosts." He said the issue has been "identified, isolated and a fix has been deployed."
Microsoft said in a statement on X that "the underlying cause has been fixed," however, residual impacts continue to affect "some Microsoft 365 apps and services. We're conducting additional mitigations to provide relief."
Developments:
∎ The Federal Aviation Administration said in a statement on X that it's "closely monitoring a technical issue impacting IT systems at U.S. airlines" and that several airlines "have requested FAA assistance with ground stops until the issue is resolved."
∎ Dubai International Airport said on X that it is operating normally following "a global system outage that affected the check-in process for some airlines." It added that the affected airlines "promptly switched to an alternate system, allowing normal check-in operations to resume swiftly."
∎ German University Medical Center Schleswig-Holstein, one of the largest medical facilities in Europe said in a statement on its website that it's halting all elective procedures on Friday and closing its outpatient clinics. Emergency care remains guaranteed, the statement, which cited the Crowdstrike-related outage, said.
