To answer Matt’s question, NO. Assume Cogent peers with NTT. Assume Google peers with NTT. NTT has very good v6 connectivity (not an assumption).
Cogent cannot send a packet to NTT and say “please hand this to Google”. Nor can Google hand a packet to NTT with a destination of Cogent. Under this scenario, NTT is not being paid by Cogent or Google. Why would they take a packet from one and give it to the other? -- TTFN, patrick > On Feb 24, 2016, at 2:53 PM, Max Tulyev <max...@netassist.ua> wrote: > > If you connected to Internet ONLY through Cogent - there is no other > way.
