Unable to access Microsoft 365 services
Yep. Looks like Microsoft 365 is down again.
The official report (as of this moment):
Affected users are unable to authenticate to and access Microsoft 365 services… Dynamics 365, LinkedIn, and other services that leverage Azure Active Directory (AAD) are or were also affected by this event… This issue may potentially affect any of your users attempting to access Microsoft 365 services.
Start time: Tuesday, January 29, 2019, at 9:15 PM UT. [That’s 4:15 pm in New York.]
Preliminary root cause: A portion of third-party managed network infrastructure that facilitates authentication requests and access to Microsoft 365 services was degraded.
Can’t help but wonder if this is related to the sporadic Microsoft Update Catalog outages we’re seeing.
