Azure cluster creation and modification impaired

This incident has been resolved.

Azure is no longer experiencing capacity issues in eastus.

Due to capacity issues in the Azure East US region, some cluster operations such as cluster creation and modification may fail if East US is the target region.

Azure cluster creation is now operational. Some existing clusters will be updated during their pre-scheduled maintenance windows to fix cluster modification on those clusters.

Due to a change made by our cloud provider, cluster creation and cluster modification operations on Azure (only) are currently impaired while we prepare a fix.
