Luware - All Clusters - Elevated Graph Response Times – Incident details

Microsoft has completed the rollback. Continued monitoring by Luware confirms that the issue has not reoccurred.

Microsoft is in the ongoing process of rolling back changes. Luware Engineers are working closely with Microsoft's support team to ensure a full resolution and will share any related news as they become available.

Microsoft has reported implementing changes to mitigate the root cause. Nimbus telemetry shows that the situation has improved but is not yet fully back to normal. There has been no impact to the running of Nimbus components, but customers may notice intermittent degraded performance in areas which rely on Microsoft Graph. Luware Engineers are tracking the situation closely and we will share an update when we have further news to share.

Microsoft has published a related incident in the Azure Portal under reference TM1286773, related to availability of inbound calls in Teams. Our telemetry reports that Graph responsiveness is returning to normal thresholds and our engineers are continuing to monitor the situation.
