That appears to be a strange desire. If you need such high levels of "never
allow a normal retry" you might look at using either Prolexic or Akami services
to create a geographically-diverse network topology. Or even a simple 3DNS or
router package at your borders with a few inner-DMZ systems to handle the load.
Using http to determine if DNS services are running is a very unusual
complication.
