So now everyone will start sending test DNS requests to the servers
and overload them even further.

Does anyone have any helpful figures on how testing is causing
its own problems? I hear this shadowy complaint from time to
time -- and yet I am skeptical. Unless you go severely overboard
in the frequency of your testing, it should be only a drop in
the bucket.
How many times do my DNS servers query the root servers? Maybe
25,000 times a day? Or maybe 10 times that? What does a check
cost?
I've done parsing of the DNS server logs to avoid such things
in the past, but I don't see it as that big of a deal.
