Over 1,000 flights have been cancelled, with others delayed, following a global Windows outage, reportedly caused by cybersecurity firm CrowdStrike on Friday.
As computer systems crashed around the world, people not only came face to face with Microsoft’s BSOD (the « blue screen of death ») but businesses including airlines saw their systems go down. Reports of delays at airports from Los Angeles to Bangkok, London to Hong Kong, Mumbai to Madrid, Singapore to Melbourne, Berlin and more are pouring in on social media and through direct messages from the airlines.
While Microsoft and CrowdStrike have acknowledged the outage and are reportedly working on it, there’s the colossal issue of thousands of travellers wondering whether their flight has been cancelled or not.
The official X (formerly Twitter) account of the U.S. Federal Aviation Administration posted on Friday morning it was « closely monitoring a technical issue impacting IT systems at U.S. airlines » and suggested people monitor the FAA’s website for updates.
Here’s a list of affected airlines and their latest update. Check your email for any direct updates from the airline.
