 Azure Cache for Redis distributes nodes in a zone redundant cache in a round-robin manner over the selected Availability Zones. It also determines the node that serves as the primary initially.
 
-For Standard and Premium deployments where you selected **Select zones automatically**, the zones are selected automatically.

 #### Zone Down Experience for Premium tier
 
 A zone redundant cache provides automatic failover. When the current primary node is unavailable, one of the replicas takes over. Your application may experience higher cache response time if the new primary node is located in a different AZ. Availability Zones are geographically separated. Switching from one AZ to another alters the physical distance between where your application and cache are hosted. This change impacts round-trip network latencies from your application to the cache. The extra latency is expected to fall within an acceptable range for most applications. We recommend you test your application to ensure it does well with a zone-redundant cache.

 A Premium cache has one primary and one replica node by default. To configure zone redundancy for more than two Availability Zones, you need to add [more replicas](cache-how-to-multi-replicas.md) to the cache you're creating.
