Is anyone else having trouble accessing Azure, Entra ID, or Microsoft 365 portals? The issue started a few minutes ago and appears to affect sign-ins and reauthentication, with users reporting SSO failures, 503 Service Unavailable errors, and Bad Gateway messages. Reports are coming from multiple locations in the United States, especially the Eastern time zone.

This appears to be a broader Entra authentication incident affecting users in the eastern United States. We’re seeing 503 and Bad Gateway responses when people try to reauthenticate.
It looks like service is starting to recover now, although some users may still see errors while existing sessions and sign-ins stabilize.
We’re getting 503 errors when authenticating to Microsoft 365 services and the admin centers. It doesn’t look isolated to one tenant.
Seeing the same thing here. Single sign-on is failing across several services, and users are being prompted to authenticate again without successfully getting through.
