What Cloud SQL does - and how it fails

Cloud SQL runs managed MySQL, PostgreSQL, and SQL Server - and sits at the bottom of most request paths, so a few minutes of connection failures cascade into full application outages upstream. Incidents typically look like connection failures to a subset of instances, slow failovers, or maintenance surprises rather than region-wide loss.

  • Connection failures or timeouts to a subset of instances in one region
  • High-availability failovers taking longer than the expected ~60–120 seconds
  • Storage or IOPS degradation making queries slow, not failed
  • Connectivity-path issues (Cloud SQL Auth Proxy, Private Service Connect) that look like database outages

Cloud SQL questions

Is Cloud SQL down right now?

Check the live status above. If Cloud SQL shows Operational but your database is unreachable, check whether an HA failover just moved your instance, and verify the auth-proxy/connector path - connector failures are indistinguishable from database failures to your app.

Does high availability protect me from Cloud SQL outages?

An HA (regional) instance survives zone failures via automatic failover with a brief interruption. It does not protect against region-level events or issues in the shared control plane - for those you need cross-region read replicas and a promotion runbook you have actually tested.

What SLA does Cloud SQL carry?

HA-configured instances carry a 99.95% monthly uptime SLA (Enterprise Plus edition targets 99.99%). Single-zone instances carry no SLA. Credits are tiered, must be claimed within 30 days, and cap at 50% of the monthly charge.
