Latest Message<\/th>\nTitle: Users may see delays in alerts for some kinds of activity in the Microsoft Defender portal<\/p>\n

User impact: Users may have seen delays in alerts for some kinds of activity in the Microsoft Defender portal.<\/p>\n

Final status: We were alerted to an issue by our internal monitoring systems for Microsoft Defender. Upon investigating the service, we determined that a recent change made to the affected infrastructure that supports alerts contained a code issue, which led to impact. We reverted this code change and after monitoring our service telemetry, we confirmed that delays had decreased and service health returned to normal.<\/p>\n

Scope of impact: Any users serviced by the affected infrastructure may have seen delays in specific security alerts for some kinds of activity in the Microsoft Defender portal.<\/p>\n

Start time: Wednesday, March 19, 2025, at 10:00 PM UTC<\/p>\n

End time: Thursday, March 20, 2025, at 4:42 AM UTC<\/p>\n

Root cause: A recent change made to the affected infrastructure that supports alerts contained a code issue, which led to impact.<\/p>\n

Next steps:
– We’re reviewing the affected service infrastructure to identify improvements that can be made to detection, testing, and validation, to help prevent similar issues from occurring in the future.<\/p>\n

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