What Happened?/Global Computer Crowdstrike
On Friday, computer systems around the world broke down. This affected services at airlines, banks, and the London Stock Exchange. A popular cybersecurity program failed, and Microsoft had problems with its cloud services.
What Caused the Problems?
CrowdStrike Holdings Inc. told customers that its Falcon Sensor product was making Microsoft’s Windows crash. The exact cause was unclear. These problems happened at the same time as issues with Microsoft’s Azure cloud and 365 office services. Microsoft said, “We know about an issue affecting Windows devices due to an update from another company’s software. We expect to fix it soon.”
Rare Scale of the Outage
Big outages like this are rare. Alan Woodward, a cybersecurity professor, said it was unprecedented and would have a huge economic impact.
More businesses are moving services online to save costs and improve operations. In 2017, Amazon’s cloud service errors disrupted many websites like ESPN.com. In June 2021, Fastly, a content delivery network, had issues that took down sites like the New York Times and Reddit for a day. Later that year, Amazon’s AWS cloud service problems affected Disney theme park visitors, Ticketmaster’s Adele ticket sales, and Tinder.
Major Companies Affected
On Friday, companies like McDonald’s, United Airlines, and the London Stock Exchange reported issues. KLM suspended most flights due to a global computer outage.
