Microsoft outage drew 7.4 million DownDetector reports

DownDetector said reports of errors affecting Microsoft services peaked at 19,650 per minute, more than 1,500 times the usual level. Users were still reporting problems nearly 24 hours after the outage began.

Outlook and other Microsoft enterprise services were unavailable for more than 24 hours, longer than an 11-hour outage in August, according to Mashable. By late Friday afternoon, the disruption appeared to be easing, but Microsoft had not given an estimated time for full recovery.

The report’s figures carry a caveat: DownDetector counts user reports, rather than independently verified service failures. Companies have disputed its data before. Amazon Web Services, for example, challenged DownDetector’s display of problems with AWS on Thursday, when Outlook was also experiencing an outage. Mashable said Microsoft declined to comment on the Ookla report.
