 - **Automatic failover policy**
 
   By default, a failover group is configured with an automatic failover policy. The SQL Database service triggers failover after the failure is detected and the grace period has expired. The system must verify that the outage cannot be mitigated by the built-in [high availability infrastructure of the SQL Database service](sql-database-high-availability.md) due to the scale of the impact. If you want to control the failover workflow from the application, you can turn off automatic failover.

+  > [!NOTE]
+  > Because verification of the scale of the outage and how quickly it can be mitigated involves human actions by the operations team, the grace period cannot be set below one hour.  This  limitation applies to all databases in the failover group regardless of their data synchronization state.
