Microsoft Sentinel Service Degradation
ResolvedMajor outage3 hours 31 minutes
  • ResolvedUTC

    Hello,

    Microsoft has reported that the Sentinel service issue affecting incident investigations and automation delays is now mitigated. Normal business operations will continue.

    We are retrospectively reviewing Sentinel alerts from the affected period to identify any that were delayed or not delivered. If we identify any customer-relevant alerts, we will share them with you.

    We will continue to monitor the situation and provide further updates if needed.

    Thank you for your understanding.

  • InvestigatingUTC

    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.

    11:11 Systems will be performing maintenance to upgrade the Purity version on the Pure array that supports the storage environment. This work is necessary to make sure the array has the latest security patches and bug fixes, and to ensure continued performance and reliability of the platform. Our engineering team and Pure support will complete this as a non-disruptive procedure, two redundant controllers will be upgraded one at a time.

    11:11 Systems engineers are aware of an issue affecting the managed database monitoring system. We have been working on an internal project to migrate customers to a new monitoring platform, but due to the issue, we are accelerating that migration. Additional updates will be provided as information becomes available.

    Until the migration is complete, you will not receive monitoring alerts. Once your monitoring has been migrated, alerts will be generated in the 11:11 Account Management Application.

    All affected customers will be receiving ticket communication.
