Latest Message<\/th>\nTitle: Admins may experience delays of up to two hours for some security alerts within the Microsoft 365 Defender portal<\/p>\n

User impact: Admins may have experienced delays of up to two hours for some security alerts within the Microsoft 365 Defender portal.<\/p>\n

Final status: We’ve rebalanced traffic loads and cleared the backlog of accumulated requests, and have confirmed after monitoring telemetry that the service has returned to expected functionality.<\/p>\n

Scope of impact: Any admin attempting to view security alerts within the Microsoft 365 Defender portal may have been impacted.<\/p>\n

Start time: Wednesday, February 21, 2024, at 12:00 PM UTC<\/p>\n

End time: Wednesday, February 21, 2024, at 8:25 PM UTC<\/p>\n

Root cause: A portion of our monitoring system that’s responsible for automatically rebalancing traffic was operating below expected standards, causing an imbalance on traffic loads as the metrics pulled from the affected monitors weren’t accurate, resulting in a backlog of requests to accumulate and delays of up to two hours for some security alerts.<\/p>\n

Next steps:
– We’re reviewing our monitoring system to identify what caused it to operate below expected standards so we can prevent similar issues from occurring in the future.<\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
