 Some Azure services use paired regions to build their multi-region geo-replication and geo-redundancy strategy. For example, [Azure geo-redundant storage](../storage/common/storage-redundancy.md#geo-redundant-storage) (GRS) can automatically replicate data to a paired region.

+If you're in a region that's paired, then using its pair as a secondary region provides several benefits:
 
 - **Region recovery sequence**. In the unlikely event of a geography-wide outage, the recovery of one region is prioritized out of every region pair. Components that are deployed across paired regions have one of the regions prioritized for recovery.
 - **Sequential updating**. Planned Azure system updates are staggered across region pairs to minimize the impact of bugs or logical failures in the rare event of a faulty update, and to prevent downtime to solutions that have been designed to use paired regions together for resiliency.
