Microsoft Outlook, Teams and 365 hit by widespread outage

What happened

Microsoft ran into a broad service disruption in North America that, per Downdetector.com, impacted thousands of users. The trouble began shortly before 1 p.m. and hit Outlook, Teams and Microsoft 365. Reports on the same site indicated that users of Amazon Web Services and Google were experiencing problems as well.

What Microsoft says

A post from the Microsoft 365 Status account on X shortly after 1:30 p.m. ET said parts of the company's infrastructure were under higher than normal load across several regions, which likely contributed to users' connection problems. Microsoft later said the outage stemmed from a rise in unavailable servers and that it initiated restarts of the affected servers. The company added the shutdown could be tied to failed health checks linked to a specific component that handles server health. It also said it has put safeguards in place to keep more servers from being affected while it brings impacted machines back online.
