Whomever hurts the most will blink first. I don't really care who that is. I have no ill will towards "double dipping". 
Either they do or they don't offer the desired connectivity and I'm moving on.

Are HE & Google the new L3 & FT? 

Nah, L3 would never have baked Cogent a cake. :) 

Shall we start a pool? Only problem is, should the pool be “who will disconnect from Cogent next?” or “when will Cogent 
blink?” I’m voting for the former.

This is Google saying that Google does not want to pay for traffic to 
Cogent. If Cogent wants to exchange any traffic with Google, Cogent is 
invited to peer directly with Google. Of course Cogent refuses. And now 
Cogent is not only missing the part of IPv6 internet that is Hurricane 
Electric single homed but also everything Google. 

Why does Cogent refuse? They used to deliver this traffic on free peering 
with another tier 1 provider. Now they are asked to deliver the same 
traffic for the same price (free) on a direct peering session. They won't 
because Cogent believes Google should pay for this traffic. That another 
Cogent customer already paid for the traffic does not matter. They want 
double dipping or nothing. So nothing it is. 

Seems to me that if you are serious about IPv6 you can not use Cogent as 
your primary or secondary transit provider. You can use them as your third 
if you want to.

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
