Latest Message<\/th>\nTitle: Users may be unable to access Threat Explorer or Advanced hunting and receive an error<\/p>\n

User impact: Users may have been unable to access Threat Explorer or Advanced hunting and received an error.<\/p>\n

Final status: We\u2019ve completed processing the backlog of mail metadata updates and observed from our service telemetry that the errors and latency are resolved, confirming that the impact is remediated.<\/p>\n

Scope of impact: Users located in North America who were attempting to access Threat Explorer and Advanced hunting may have been impacted.<\/p>\n

Start time: Tuesday, October 21, 2025, at 6:59 PM UTC<\/p>\n

End time: Thursday, October 23, 2025, at 11:40 PM UTC<\/p>\n

Root cause: A change in traffic pattern in a section of infrastructure responsible for regulating access to Threat Explorer and Advanced hunting caused impact to occur.<\/p>\n

Next steps:
– We\u2019re analyzing performance data associated with the impacted section of infrastructure responsible for regulating access to Threat Explorer and Advanced hunting to assist us in understanding the change in traffic pattern that caused impact and in preventing the inability to access Threat Explorer and Advanced hunting from happening again.<\/p>\n

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