Meant to add one thing... In our configuration, we actually have two
recursive VIPs per site, and even considered three (internal IPs are cheap).
We do this.
We also make the two different VIPs use different underlying tech - one
is an anycast route advertised with eBGP, the other is via
load-balancing. The diversity of tech gives us a bit more resilience and
flexibility - taking out the load-balancer no longer destroys DNS, for
example.
