Summary of Impact: Between 11:49 EST on 01 March 2022 and 03:08 EST on 03 Mar 2022, a subset of customers experienced errors when using Azure Resource Manager to perform service management operations in the Azure Government cloud.
Root Cause: A synchronization issue occurred between backend components used to permit certain ARM requests. A configuration change was applied to these backend components, which resulted in some instances of the ARM service becoming unreachable, causing errors for a subset of operation requests.
Mitigation: We rolled out a hotfix to affected components, restoring the ARM service, which allowed operation requests to complete as expected.
Next Steps: We apologize for the impact to affected customers. We are continuously taking steps to improve the Microsoft Azure Platform and our processes to help ensure such incidents do not occur in the future. In this case, this includes (but is not limited to):
- Update ARM component configuration methods to help prevent synchronization issues when similar updates are required.
