Xbox Live has gone down, leaving users unable to log in, play their downloaded games, or access the store.
The issue appears to have started shortly after 8.30am, with hundreds of people logging complaints with online outage tracker Down Detector.
It appears to be connected to a wider outage affecting Microsoft, with thousands of users reporting that services including Outlook, Teams, Bing and Microsoft 365 have also gone down.
The outage comes at a terrible time for gamers, amid the hotly-anticipated release of Call of Duty: Modern Warfare 3.
“Is everything down this morning? Bing not working and can’t play games on my Xbox One X?” one person commented on X, formerly Twitter.
Another added: “Nothing owned or operated by Microsoft is working. Outlook, Xbox, store all down.”
Despite the outage, as of 10.30am the Xbox Status website was not reporting any problems, and the Xbox Support X account is yet to reply to any posts, so there is no word on when the problems may be fixed.
i has contacted the Xbox team for comment.
