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?
