I've dug this up 2-3 times since 2001 and I always have a nightmare of a time finding it. I'm not finding it anywhere right now. I'm pretty sure it was a Nanog report but I could be wrong there, it was very thorough and a lot of slides.

Best I can do right now is the Nanog mail list that day/week... https://archive.nanog.org/mailinglist/mailarchives/old_archi...
