This page describes operations that impact availability in Cloud SQL.
Cloud SQL helps you maximize the uptime of your database without any changes to your application. With a 99.99% uptime SLA, Cloud SQL Enterprise Plus edition offers greater resilience and business continuity for your applications.
For unplanned events such as a failure of one or more infrastructure components within a zone*, Cloud SQL high availability (HA) brings up the database in the secondary zone with the same IP address and no data loss so that applications can resume operations on the database. Cloud SQL high availability is also available for Cloud SQL Enterprise edition. For more information about configuring availability in Cloud SQL, see About high availability (HA).
* The Mexico, Montreal, and Osaka regions have three zones within one or two physical data centers. These regions are in the process of expanding to at least three physical data centers. For more information, see Cloud locations and Google Cloud Platform SLAs. To help improve the reliability of your workloads, consider a multi-regional deployment.
