WASHINGTON: Air passengers around the world faced delays, cancellations and problems checking in as airports and airlines were caught up in a massive IT outage that also affected industries ranging from banks to media companies.
The travel industry was among the hardest hit with airports around the world, including Tokyo, Amsterdam, Berlin and several Spanish airports reporting problems with their systems and delays.
International airlines, including Ryanair, Europe’s largest airline by passenger numbers, warned of problems with their booking systems and other disruptions.
According to an alert sent by Crowdstrike to its clients and reviewed by Reuters, the company’s “Falcon Sensor” software is causing Microsoft Windows to crash and display a blue screen, known informally as the “Blue Screen of Death”.
The alert, which was sent at 0530 GMT on Friday, also shared a manual workaround to rectify the issue.
A Crowdstrike spokesperson did not respond to emails or calls requesting comment.
There was no information to suggest the outage was a cyber security incident, the office of Australia’s National Cyber Security Coordinator Michelle McGuinness said in a post on X.
The outages rippled far and wide, wreaking havoc on global computer systems. Microsoft users worldwide, including banks and airlines, reported widespread outages, hours after the technology company said it was gradually fixing an issue affecting access to Microsoft 365 apps and services.
The cause, exact nature and scale of the outage was unclear. Microsoft appeared to suggest in its X posts that the situation was improving but escalating outages were still being reported around the world hours later.
The UAE’s Telecommunications and Digital Government Regulatory Authority issued a statement, warning Crowdstrike users of a “technical issue” with the “software update.”
“We advise users of the program to hold off on any updates or downloads of CrowdStrike software until the issue is resolved.”
