Interesting - So as a cyber criminal - I could setup a router, start announcing AS 16733, 18872, and maybe 6966 for good measure and their routers would ignore my announcements and IP ranges that I siphoned from searching IANA? Hm... Would that also prevent them from accessing my rogue network from their network? - Michienne Dixon Network Administrator liNKCity 312 Armour Rd.

Their announcement was "odd" in some way, but appeared clean to us (a Cisco house). Once their announcement hit the a Foundry router, it tickled a bug which caused the router to propogate the announcement, but also start to blackhole traffic. Oh dear, large chunks of the Internet have just gone belly up. Should we have given a heads up to the Internet at large that we were turning up this customer?
