Because it is not the place of a connection management software
to failover. Failover should happen only if:
1. You have a specific set of criteria that is matched via a network/system
management software.
2. You do it yourself.
The last thing in the world you need is to fail over to a slave because
somebody accidently tripped over a network cord.
