Latest Message<\/th>\nTitle: Users may be missing some device timeline and advanced hunting events in the Microsoft Defender for Endpoint portal<\/p>\n

User impact: Users may be missing some device timeline and advanced hunting events in the Microsoft Defender for Endpoint portal.<\/p>\n

More info: This issue only impacts some workstation endpoints and not servers.<\/p>\n

Current status: We’ve experienced an unexpected delay with the system restarts so the rollback changes are applied across the affected infrastructure to fully remediate impact, and estimate that this will complete by our next scheduled update.<\/p>\n

Scope of impact: This issue may impact some users’ workstation, and some device timeline and advanced hunting events may be missing in the Microsoft Defender for Endpoint portal.<\/p>\n

Start time: Wednesday, September 3, 2025, at 5:09 AM UTC<\/p>\n

Root cause: A recent change to provide updates to the mechanism of data collection for timeline and advanced hunting events is resulting in impact.<\/p>\n

Next update by: Saturday, September 27, 2025, at 5:30 PM UTC<\/td>\n<\/tr>\n
