I think using DNS to load balance is what was meant, PowerDNS can do this,
but most DNS servers can to basic load balancing/round robin (it will just
give out a different/multiple A Records each time. I've done this with bind
and Microsoft before.

PowerDNS has an awsome geolocation plugin, and that probably can be tied to
a check to see if the IP is up so it's actually checking the status of IPs
to make it more automated.
