Description: We are experiencing an issue with Cloud SQL API instance mutations and SQL Proxy operations in us-central1. We believe impact began at 08:50 US/Pacific with the error rate increasing starting at 09:25 US/Pacific.
Our engineering team continues to investigate the issue. Instance mutation operations (such as instances.create or instances.delete) as well as requests for certificates (sslCerts.createEphemeral) when using Cloud SQL Proxy are impacted. Existing connections to Cloud SQL instances should be unaffected. New connections without Cloud SQL Proxy are also unaffected.
The product team has identified a potential mitigation and is working to implement it. We believe the change will be finished rolling out by 15:00 US/Pacific, we will be continuously monitoring the service to evaluate the effectiveness of the mitigation.
We will provide an update by Friday, 2021-01-29 15:30 US/Pacific with current details.
