Summary: Cloud Bigtable is experiencing issues with CopyBackup, RestoreTable, and CreateCluster operations with some zones as the target zone. Description: We are experiencing an issue with Cloud Bigtable CopyBackup, RestoreTable, and CreateCluster operations using some zones as the target zones beginning at Monday, 2023-10-23. Our engineering team is working to investigate the issue. We will provide an update by Wednesday, 2023-10-25 12:30 US/Pacific with current details. We apologize to all who are affected by the disruption. Diagnosis: - Cloud Bigtable CopyBackup may fail when copying to a cluster in the affected zones, - RestoreTable may fail when restoring to an instance with cluster in the affected zones, and - CreateCluster operations may fail. Following are the AFFECTED ZONES asia-east1-b, asia-east2-c, us-central1-c, and us-west2-a Workaround: The following workarounds are available: CreateCluster: - Create the cluster in an unaffected zone CopyBackup: - Create a new cluster or select an existing cluster in an unaffected zone - Copy the backup to the above cluster RestoreTable: - Create a new instance or select an existing instance in an unaffected zone - Restore the backup to the above instance
