User impact: Admins may have been unable to render portions of the Microsoft 365 admin center.

More info: Although admins may have been able to access the Microsoft 365 admin center, they may have seen that individual sections, such as the navigation menu to access service-specific admin centers, were blank or not functional.

After confirming with some affected admins, as well as monitoring telemetry, we’ve confirmed that our efforts to rebalance traffic has successfully remediated impact.

Scope of impact: This issue may have affected any admin accessing the Microsoft 365 admin center.
