Cogent & Google IPv6

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.

Regards,

Baldur
