Just info for those who may find it useful...

There is a custom patch for BindBackend2 of PowerDNS that makes this
DNS-level loadbalancing and failover possible. One can assign weights to A
records and also keepalive watches so that "dead" addresses aren't served.
It's configurable directly in zone through special TXT records. Find it at
