Hi Dennis,

It's Cogent's fault because: double-billing. Google should not have to
pay Cogent for a service which you have already paid Cogent to provide
to you. Cogent's demand is unethical. They intentionally fail to
deliver on the basic service expectation you pay them for and refuse
to do so unless a third party to your contract also pays them.

Google, by contrast, makes no demand that Cogent pay them even though
you are not paying Google for service. They offer "open peering," a
free interconnect via many neutral data centers.

If you're not single-homed to Cogent and you have the balls for it, I
would file an outage with Cogent and demand service credit until they
resolve their IPv6 access problem with Google. And then refuse to pay
until they connect with Google.

If you are single-homed to Cogent, it's *very* important that you do
something about that before you get burned in a way that matters.
