Anyone who is multihomed with cogent ipv6 in their mix should shutdown their IPv6 bgp session. Let’s see if we can make their graph freefall.

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.
