The official Microsoft 365 Service Health Status website currently lists there is no issue with "everything up and running". However, the page will likely be updated soon to reflect the situation.
From the user comments on the M365 Status X thread, it appears that the Microsoft 365 Admin Center portal is also inaccessible and the session may be getting signed out as well as a result of this issue.
We will update the post once more details are available.
