RedirectorController Placement
Proper placement of RedirectorController instances (controllers) in your
messaging environment is essential for high-availability failover. Much like the
domain name service (DNS), the controllers provide routing information to the
Exchange servers for active users. Without access to RedirectorControllers, the
RedirectorSinks cannot redirect messages for active users. Similarly, without
access to the data center, RedirectorControllers cannot obtain updated routing
information for transmission to the RedirectorSinks.
