Many thanks. pardon my ignorance here, but question: For an outfit such as Cogent which acts not only as a transit provider, but also edge provider to large end users, can it easily implement such a court order to block only edge interfaces and not to its transit infrastructure? (aka: propagate null routes for 104.31.19.30 only to interfaces that lead to end users, but leave core/GBP aspects without the block.) Or is BGP and any internal routing protocols so intermingled that it becomes hard to manage such blocks ? The difficulty for network to block traffic becomes an important argument when trying to convince governments that blocking should not be done. (ex: Québec government wanting to block access to gambling sites except its own).
