Why do these kind of failover setups at all? When I create these
failover setups they work perfectly during tests but fail during real
failures. With round robin A records, NAPTR and SRV you can have
multiple live servers. Only the endpoints what actually use a hardcoded
ipaddress will have problems in the case of a failure. 

The added benefit is scalability and easy maintenance.

The bad is there isn't a wiki entry on how to do it AFAIK.

BTW the shared database seems to be a bit deprecated (and a common point
of failure), look at DMQ if you have to start from scratch.
