There is some misinformation in previous posts that I would like to clarify on the Level 3 side of things.
and I'd apologize for hinting that that might be the problem :(
Level 3's own registry and known public route registries. As several folks have pointed out there are minimal checks for the validity of the source information.
this was what bit panix/edison I believe... :(
As an aside I see an increase in the number of downstreams asking for as-path filtering or *no* filtering usually with justifications of ISP X doesn't require us to register routes or just does as-path filtering. In my opinion that is bad news for everyone as documented in numerous BCPs, presentations and route-leaks.
agreed, there is this trend, it's disturbing :( (to me atleast) In the number of customer conversations I've had about this it's always sort of surprising that people think it's 'ok' to not have a prefix-list :( cause, guess what: "if you don't have one and they don't have one... THEY will get you eventually"
