Yes, it's a global Cogent problem. We are in contact with them as well and were told that they're aware of that but can't do anything about it on their own.

Dear Cogent Customer,

Cogent NOC team has been working with Verizon as well as Google to assist with resolving the issue. After further 
investigation there is no issue on the Cogent network which is causing the issue that you are seeing. Currently we have 
asked for  Google and Verizon to work together to assist with resolving the issue which has been isolated to their end 
of the spectrum.

As you can see, this issue is beyond Cogent control nevertheless, we continue pushing to get it resolve. We will 
provide you with further updates as they arise.

I am getting a "Destination unreachable" from their closest router. We did rerouting through a different carrier, so not a big problem for us, but still annoying.

# ping6 ipv6.google.com
PING ipv6.google.com(dfw06s47-in-x0e.1e100.net) 56 data bytes
   From te0-0-0-1.rcr12.sea03.atlas.cogentco.com icmp_seq=1 Destination
unreachable: No route

I am currently having a issue with cogent and google over ipv6. My traceroute seems to hit cogent, Verizon, and then 
just dies.

I have a case open with both and each tells me the other is working on it.

If my telepathy still works fine and I understood your question well - then the answer is "NO, that is not a global 
well-known issue" ;)
