Incident Start: 09 December 2022 04:50

Incident End: 09 December 2022 07:55

Duration: 3 hours, 5 minutes

Affected Services and Features:

• Artifact Registry: New repository creations
• Google Cloud Composer: Composer environment creations
• Google Cloud Storage: Operations that check IAM policies, especially CreateBucket
• Google Kubernetes Engine: New cluster creation
• Identity and Access Management: Not directly affected, only downstream services.

Regions/Zones: australia-southeast1, asia-east1, asia-east2, asia-northeast1, asia-northeast2, asia-northeast3, asia-south1, asia-south2, asia-southeast1, asia-southeast2, australia-southeast2, and asia (Google Cloud multi-region).

Description:

Google Cloud Identity and Access Management (IAM) in the Asia multi-region experienced unavailability, which impacted several downstream Google Cloud services for a period of 3 hours and 17 minutes. Customers directly using IAM were not affected. The root cause was related to a configuration change with unintended consequences, which was immediately rolled back, once identified as the problem, thereby restoring services.

Customer Impact:

Artifact Registry

• Affected customers would not have been able to create new repositories in the Asia multi-region. Customers would have received a failure message of “Request contains an invalid argument.”

Google Cloud Composer

• Affected customers in the Asia multi-region were not able to create Composer environments, receiving errors indicating either an issue with AppEngine or Google Kubernetes Engine (GKE) cluster creation.

Google Cloud Storage

• Affected customers would have experienced increased error rates when creating buckets in the Asia multi-region. GKE uses Google Cloud multi-regional buckets internally, so regional GKE customers throughout Asia Pacific were affected.

Google Kubernetes Engine

• Affected customers would have been unable to create new clusters in the affected regions.

If you have questions or are impacted, please open a case with the Support Team and we will work with you until this issue is resolved. No further updates will be provided here. We thank you for your patience while we are working on resolving the issue.
