Latest Message<\/th>\nTitle: Users may be unable to view updates for time travel events in Microsoft Defender XDR pages<\/p>\n

User impact: Users may be unable to view updates for time travel events in Microsoft Defender XDR pages.<\/p>\n

More info: Affected pages include, but aren’t limited to:<\/p>\n

– Threat Explorer
– Advanced Hunting<\/p>\n

Current status: We’ve identified that a false positive recovery was initiated for a widely-used domain entity, which triggered a surge in Time Travel (TT) recovery events, overwhelming the ingestion pipeline and causing delays in metadata visibility. The backlog of TT events is being monitored as it clears and we anticipate to be able to provide a remediation timeframe by our next scheduled update.<\/p>\n

Scope of impact: Impact is specific to some users who are served through the affected infrastructure.<\/p>\n

Start time: 26 August 2025 at 7:00 AM UTC<\/p>\n

Root cause: A false positive recovery was initiated for a widely-used domain entity, which triggered a surge in TT recovery events, overwhelming the ingestion pipeline and causing delays in metadata visibility. <\/p>\n
