DownDetector, which tracks the online status of most major online services, reported that Microsoft Outlook, Microsoft 365, Microsoft Copilot, OneDrive, and Microsoft Teams all were suffering outages, as reported by users. However, those weren’t the only affected, as the service also reported similar spikes in outages from Amazon, Facebook, Salesforce, Anthropic’s Claude, Slack, and Reddit.

“While we’re working to mitigate impact, we’ve confirmed the issue may affect Microsoft 365 service connectivity for users in any region,” the Microsoft 365 status account reported.
DownDetector’s findings weren’t immediately reproduced by the services themselves.
The CloudFlare Radar service noted no issues. Google’s cloud status page also reported no issues. Amazon’s AWS Health Dashboard only noted a localized problem in its Tokyo cloud service.
So far, a root cause has yet to be identified.
