Partial Actions Cache degradation

This incident has been resolved. Thank you for your patience and understanding as we addressed this issue. A detailed root cause analysis will be shared as soon as it is available.

We are continuing to rollout a mitigation and are progressing towards having this rolled out for all customers.

We are currently deploying a mitigation for this issue and will be rolling it out shortly. We will update our progress as we monitor the deployment.

We are actively investigating and working on a mitigation for database instability leading to replication lag in the Actions Cache service. We will continue to post updates on progress towards mitigation.

The actions cache service is experiencing degradation in a number of regions causing cache misses when attempting to download cache entries. This is not causing workflow failures, but workflow runtime might be elevated for certain runs.

We are currently investigating this issue.
