I think you're failing to take into account how multihoming generally works. The real fallacy here is that PCCW/BTN refuses to prefix-list filter their customers, as evidenced by this and past leaks. If something productive can come from today's outage, it would be PCCW beginning to do their part as responsible Internet citizens, given (excuse the pun) "peer" pressure. I'd also focus on the lessons learned from the un-official "IP Hijacking BOF" held in San Jose, during which engineers and researchers studied the extent to which obviously-bogus route advertisements propagated across the public Internet. At these events, prefixes such as 1/8 and 100/7 were advertised, and, by Renesys/bgplay/route-views/etc data, accepted by >99% (?) of the internet. IP blocks that were hijacked before (like 146.20/16) were announced with similar outcome. Results were planned to be presented at the next NANOG, but they shouldn't be a surprise to anyone in the industry: nobody filters. Paul Wall
