 ## Subscribing to event notifications
 
+<Note> 
+
+  Vault deployments with performance replication must subscribe to events on the
+  primary performance cluster. Vault ignores subscriptions made from secondary
+  clusters.
+
+</Note>
+
 Vault has an API endpoint, `/v1/sys/events/subscribe/{eventType}`, that allows users to subscribe to event notifications via a
 WebSocket stream.
 This endpoint supports the standard authentication and authorization workflows used by other Vault endpoints.
