This has been going on nationwide between Cogent and other peering partners since early 2013 (and in some cases before), but especially between Cogent and Verizon. It's not a technical problem, but a political one.
We resolved our issue by working with our upsteam providers to reconfigure our routing and advertisements to avoid cogent, otherwise, I don't think there is any solution coming within a reasonable timeframe
