Incident Report
We are currently addressing an issue affecting some AWS VM backup jobs. Impacted jobs may fail during processing due to a signature validation error encountered while accessing data through the AWS API.
While we are working with AWS on the root cause we are actively deploying a fix on our end to work around the issue to the affected systems. We will provide another update once the deployment is complete and service has been fully restored.
