For Cloud SQL Enterprise Plus edition instances, you can now use advanced disaster recovery (DR) to simplify recovery and fallback processes after you perform a cross-regional failover

## Feature For [Cloud SQL Enterprise Plus edition](https://cloud.google.com/sql/docs/postgres/editions-intro) instances, you can now use advanced disaster recovery (DR) to simplify recovery and fallback processes after you perform a cross-regional failover. With advanced DR, you can: * Designate a cross-region disaster recovery (DR) replica * Perform a cross-region replica failover for disaster recovery * Restore your original deployment by using zero-data loss switchover You can also use switchover to simulate disaster recovery without data loss. You can use advanced DR on Cloud SQL for PostgreSQL version 12, 13, 14, 15, or 16. For more information, see [Advanced disaster recovery (DR)](https://cloud.google.com/sql/docs/postgres/intro-to-cloud-sql-disaster-recovery#advanced-dr) and [Use advanced disaster recovery (DR)](https://cloud.google.com/sql/docs/postgres/use-advanced-disaster-recovery). This feature is [generally available](https://cloud.google.com/products#product-launch-stages) (GA). ## Feature The write endpoint feature is now available in [Preview](https://cloud.google.com/products#product-launch-stages). This endpoint is a global domain name service (DNS) name. This name resolves to the IP address of the current primary Cloud SQL instance that's enabled with private services access. By using a write endpoint, you can avoid having to make application connection changes after performing a switchover or replica failover operation to test or mitigate a regional failure. For more information, see [Configure private IP](https://cloud.google.com/sql/docs/postgres/configure-private-ip#connect-write-endpoint).
