Steve,

  Those are Level(3)s anycast DNS servers - part of internet legend!

  I once talked to a Level(3) engineer about how many queries those
things do (combined) and it was amazing.  I don't remember the exact
number but it was something in the TENS OF MILLIONS/day, maybe more.
It was one of those numbers (especially for daily traffic) that you
just don't really comprehend.

  I've read (on NANOG, of course) that Level(3) actually encourages
(at least doesn't discourage) their public use.  They log the queries
and sell the results for data mining purposes (DNS Alexa perhaps).
