Failover to the secondary Amazon Region

We recommend that you monitor replication latency in the secondary Amazon Region using Amazon CloudWatch. During a service event in the primary Amazon Region, replication latency may suddenly increase. If the latency keeps increasing, use the Amazon Service Health Dashboard to check for service events in the primary Amazon Region. If there’s an event, you can failover to the secondary Amazon Region.
