It might help but isn't a cure all. 

If they can query it they can DoS it and given the splay of zombies
vs your servers there should be enough to kill them all

dns serving P2P style (I'm not suggesting someone should do it)
would even up the odds, with enough penetration you could get 1:1 so
they all attack themselves.

more useful would be to make a query that returned the answers
from all your servers (obfuscated if necessary) so we can see which
is different & have data to report the problem

I presume you have such a tool internally for regression testing
