BGP Logs
 

Found an interesting link from a friend of mine...
http://bgp.lcs.mit.edu/

They keep BGP route announcement/withdrawal logs and they seem to date back to June 2001 (the latest). Dropping in the IP of random web hosts nets funny results.

Kinda like how Cologroup had Level3 connectivity from late October 2001 to December 2001, and it hasn't resurfaced since, although it's listed as backup connectivity on the network page...
