Microsoft outage was largest of 2026, report says
DownDetector said Microsoft's big outage was, by a wide margin, the biggest of 2026.
Microsoft experienced its largest service disruption of 2026, according to a report by Ookla and DownDetector. The outage, which caused widespread issues with Outlook and other Microsoft enterprise software services, was reported 7.4 million times by users, significantly more than the 2.8 million reports for a YouTube outage in February.
During the Microsoft outage, users reported a peak of 19,650 user error reports per minute to DownDetector, which is over 1,500 times the normal level. The outage lasted for more than 24 hours, making it one of the longest in recent months. While the issue appears to be subsiding, Microsoft has not yet provided an estimated time of recovery.
