Airports across Europe also seemed to struggle.
Dutch airport Schiphol said a “global computer failure” had impacted flights. London Gatwick cited problems in the check-in procedures, citing “global Microsoft issues.” Berlin Brandenburg airport also reported delays at check-in.
Other transport companies, such as the Belgian railway company, cited IT issues impacting sales channels or online announcements.
Ryanair warned on its site that due to a “global third party IT outage” booking and check-in were unavailable.
The London Stock Exchange operated normally but said it could not publish news on its site.
Major broadcasters also reported issues preventing them broadcasting live. Several Sky employees flagged issues on X.
Users on a subreddit (a forum-like thread on aggregation site Reddit) of cybersecurity firm Crowdstrike also flagged outages. After that, the Windows crashes were linked to Crowdstrike’s Falcon platform, which fends off cyber attacks.
Microsoft and Crowdstrike didn’t immediately respond to a request for comment.
