Ntirety - Microsoft Sentinel Service Degradation – Incident details

Hello,

Microsoft is investigating an active service disruption affecting Microsoft Sentinel across multiple regions.

This is affecting our investigations in Microsoft Sentinel. Cortex XDR is not affected. Our team is manually investigating Sentinel alerts where service availability allows. Once Microsoft restores service, we will reconcile activity from the disruption period and send any customer alerts that were missed.

We are monitoring the situation and will provide another update as we learn more. We do not yet have a confirmed restoration time.

We apologize for the disruption and appreciate your understanding.
