Azure Intermittent Network Related Timeout for xDB Cloud

During daily monitoring activities, Sitecore Cloud Operations engineers found an issue with Microsoft Azure .

Root cause and mitigation: The Azure Service Management layer (ASM), that manages Classic VMs and Classic Cloud Services, is composed of multiple services and components. During this event, ASM Front ends were running low on available resources, causing some incoming requests to timeout. Engineers established that a platform service update introduced this regression that surfaced only at high incoming traffic volume. The ASM update went through the standard extensive testing and the fault did not manifest itself when the update transited through first, the pre-production environments, and later through the first Production slice where it baked for multiple days. There was no indication of such a failure in those environments during this time.

As a mitigation, the Front Ends were scaled out which restored the service health

 

Updates Summary

Resolved: 

As a mitigation, the Front Ends were scaled out which restored the service health.
