When a server loses connection to the cluster a couple of different alerts can end up being sent indicating current conditions - ie Cluster Failover, Standby Server inactive. 
When this condition occurs intermitently due to network issues it's difficult to know what the current state of the cluster is without calling or logging in to check.

What is needed is an additional notfication alert for when a node has rejoined the cluster and has replicated and gone back into standby mode.
This closes the loop in the cluster notification alerts.
