Office 365 Monitoring: Microsoft 365 Services Access Issue (Nov. 9, 2021)

On November 9, 2021, at ~10:11 am UTC, Microsoft communicated via tweet (@MSFT365status) that they were investigating an issue in which some users may not be able to access some Microsoft 365 services when using Single Sign On (SSO) apps.

If you are an IT pro with Microsoft admin center access, the issue # was MO297147.

Within the hour, Microsoft tweeted another message indicating that a recent change (no other information was disclosed other than the cryptic "recent change") was the culprit and they were working to revert the change.  Microsoft also confirmed that the impacted geo was specific to users in the central region of North America.

Approximately one hour later, Microsoft tweeted again, this time disclosing a bit more information, albeit not much, as to the cause: a recent routing configuration. Mitigation efforts were continuing at this point.

The Importance of Office 365 Monitoring

In a cloud-world, outages are bound to happen. While Microsoft is responsible for restoring service during outages, IT needs to take ownership of their environment and user experience. It is crucial to have greater visibility into business impacts during a service outage the moment it happens.
