Identified - User impact: Users may encounter delays of up to several hours for activities in Microsoft Defender for Identity.

More info: Affected users may encounter the delays for activities in the User Interface (UI) and in Advanced Hunting.

Current status: We've identified that a section of infrastructure, responsible for processing activities in Microsoft Defender for Identity, is unexpectedly performing below acceptable performance thresholds which is causing delays and a backlog of activity data. We've optimized traffic and performance parameters on the affected infrastructure to mitigate impact. However, we're monitoring the accumulation of backlogged data as it drains, and expect to have a full remediation timeline by our next scheduled update.

Scope of impact: Impact is specific to users who are served through the affected infrastructure.
