So now everyone will start sending test DNS requests to the servers and overload them even further. Dave Nordlund d-nordlund@ukans.edu
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.
