Cloud SQL v1 automated backups experiencing errors

We are investigating an issue with Cloud SQL v1 automated backups. We will provide more information by 17:30 US/Pacific.

Update 1:

The Cloud SQL service is experiencing errors on automatic backups for 7% of Cloud SQL first generation instances. We’re forcing the backup for affected instances as short-term mitigation.

We will provide another status update by 18:30 US/Pacific with current details.

Update 2:

The issue with automatic backups for Cloud SQL first generation is mitigated by forcing the backups. We’ll continue with this mitigation until Monday US/Pacific where a permanent fix will be rolled out.

We will provide next update Monday US/Pacific or if anything changes in between.
