Verizon is the one who should've noticed something was amiss and dropped their customer's BGP session. They also should have had filters and prefix count limits in place, which would have prevented this whole disaster.
oddly VZ used to be quite good about filtering customer seesions :( there ARE cases where: "customer says they may announce X" and that doesn't happen along a path expected :( For instance they end up announcing a path through their other transit to a prefix in the permitted list on the VZ side :( it doesn't seem plausible that that is what was happening here though, I don't expect the duquesne folk to have customer paths to (for instance) savi moebel in germany... there are some pretty fun as-paths in the set of ~25k prefixes leaked (that routeviews saw).
