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

If you connected to Internet ONLY through Cogent - there is no other way. If you have another upstreams - Google should be reachable.

Correct me if I'm wrong, but if Cogent isn't peering with Google IPv6, shouldn't the traffic flow out to one of their peer points where another peer DOES peer with Google IPv6 and get you in?
Isn't that how the Internet is suppose to work?

Not sure. I got the same thing today as well.
Is this some kind of ipv6 war?

Anyone know what's actually going on here? We received the following information from the two of them, and this just started a week or so ago.
*From Cogent, the transit provider for a branch office of ours:*
Dear Cogent Customer,
Thank you for contacting Cogent Customer Support for information about the Google IPv6 addresses you are unable to reach.
Google uses transit providers to announce their IPv4 routes to Cogent.
At this time however, Google has chosen not to announce their IPv6 routes to Cogent through transit providers.
We apologize for any inconvenience this may cause you and will notify you if there is an update to the situation.
*From Google (re: Cogent):*
Unfortunately it seems that your transit provider does not have IPv6 connectivity with Google. We suggest you ask your transit provider to look for alternatives to interconnect with us.
Google maintains an open interconnect policy for IPv6 and welcomes any network to peer with us for access via IPv6 (and IPv4). For those networks that aren't able, or chose not to peer with Google via IPv6, they are able to reach us through any of a large number of transit providers.
For more information in how to peer directly with Google please visit https://peering.google.com
