Is Microsoft 365 down?

The status at the top of this page comes from Hyperping checks of Microsoft 365, run every minute and refreshed on the page every 60 seconds. Green means the latest checks succeeded; red means they are failing, confirmed from several regions.

We send an HTTP request to login.microsoftonline.com every minute, in turn from Virginia, Frankfurt and Singapore, and count a successful response as up. When a check fails, other regions check again before Microsoft 365 counts as down. Outlook and Teams answer automated checks with an error page, so this page measures Microsoft sign-in, which every Microsoft 365 app depends on.

An outage can be partial: one feature, one app, one country or one internet provider, and our checks see Microsoft 365 from data centers. Try another network such as mobile data, update or restart the app, and check the official status page for an incident on one feature.

Yes, status.cloud.microsoft. Microsoft 365's team updates it by hand, so it can lag behind the start of an outage; our checks run every minute whatever it says.
