How irresponsible can you get? Advertising bogus routes, not taking any action about it when notified, obviously not having even the most minimal filters in place to prevent such things. Doesn't give me much confidence in the stability of their network or in their protections against accidental (either clueless or oops) or deliberate bogosity. Obviously, this particular instance is of little real consequence and is trivial for clueful providers to filter, but it is symptomatic of a system that may well have bigger holes large enough to drive the Titanic through as it sinks. It would be interesting to do a survey to see just how many backbone providers you can convince to advertise a really dumb route, a route for a block you don't own and is obviously in use elsewhere, etc. If this is what we see from a major backbone, what should we expect from Joe's ISP and Steak House in Mudfest Wyoming? It seems that no progress has been made, in North America as a whole, since previous incidents. Not only is it an exact reverse of one of their blocks, but it is (logically) routed there.
