[ale] Failover through DNS

[Atlanta Geek]

All,
We have a multi-server product  that we need to provide High Availability
and Geo Resilency
This will all be across a multi-location WAN

We were thinking about doing this with DNS. If one server goes down then
DNS will point to the other server.  Are there any DNS servers that have
this sort of functionality built in.  I've seen some DNS services available
that do this but we want to do it internally.
