As part of cloud infrastructure monitoring activities, Sitecore Cloud Operations team identified an event which we would like to bring to your attention. In case you have any follow up question regarding the event, please do not hesitate to raise a support case on that matter from the home page of Sitecore Support & Self-Service Portal.

Event description: We have received an update from Microsoft stating customers may have experienced degraded performance when managing resources via Azure portal or through programmatic calls between as early as 22:24 UTC on 29 Jun 2021 and 14:30 UTC on 30 Jun 2021.

Microsoft Engineers have determined that Azure Resource Manager (ARM) experienced degraded availability in a subset of regions hosting ARM endpoints. Some of the endpoints where unable to service traffic, leading to an increase in latency and call failures.

Impact: Customer might have faced performance issues while managing resources via Azure portal and programmatic calls.

Planned further actions: Microsoft took out the impacted endpoints out of rotation and redeployed new instances to mitigate customer impact and will continue to investigate to establish the root cause and prevent future occurrences.

Who performs further actions: Microsoft 

Next update planned at: No further updates
