The incident occurred on June 12, 2025, due to a policy change that contained blank fields, causing 503 errors in Google Cloud and Google Workspace APIs. The root cause was:
- A new feature added to Service Control on May 29, 2025, without adequate error handling.
- The policy change with blank fields was globally replicated and caused Service Control binaries to crash.
