 You need to be able to mitigate downtime for your application even when you're not using HA. Service downtime, like scheduled patches, minor version upgrades, or customer-initiated operations like scaling of compute can be performed during scheduled maintenance windows. To mitigate application impact for Azure-initiated maintenance tasks, you can schedule them on a day of the week and time that minimizes the impact on the application.</br>

 ## Stop replication
 
 You can stop replication between a source and a replica. After replication is stopped between a source server and a read replica, the replica becomes a standalone server. The data in the standalone server is the data that was available on the replica at the time the stop replication command was started. The standalone server doesn't catch up with the source server.

+- **Read replica for HA enabled Azure Database for MySQL - Flexible Server (General Availability)**
+
+  The read replica feature allows you to replicate data from an Azure Database for MySQL flexible server to a read-only server. You can replicate the source server to up to 10 replicas. This functionality is now extended to support HA enabled servers within same region.[Learn more](concepts-read-replicas.md)
