Remember to factor in Duane Wessel's work that showed that something like 98% of the DNS traffic at the root servers was totally bogus? Maybe you need to factor in "broken queries not answered, and offenders slapped around with a large trout"? Because if it's busted requests you're sending towards the root, they're going to count against your completed/lost ratio in a really bad way. Anybody know if people have cleaned up their collective acts since Duane did that paper?
