My guess is that GOOG is playing peering chicken with Cogent on "the IPv6 Internet" because doing so is low impact. Doing this with v4 routing would be far more painful to both GOOG and single-homed Cogent customers (probably make the news and make one or both look bad). Doing this with v6 keeps it off in the shadows...both parties know its an issue, but its likely not seriously impacting anyone yet. GOOG likely thinks they're big enough and their content desirable enough, that Cogent should peer with them. Cogent clearly disagrees. I'm sure GOOG would prefer SFI with Cogent for v4 and v6...but they're working on getting v6 first. On Thu, 10 Mar 2016, Dennis Burgess wrote:
Not wishing to get into a pissing war with who is right or wrong, but it sounds like google already pays or has an agreement with cogent for v4, as that's unaffected, cogent says google is simply not advertising v6 prefixes to them, so, how is that cogent's fault?

In other words, GOOG is playing peering chicken with Cogent for IPv6. I'm not surprised. I suggested it during talks with GOOG roughly 10 years ago...not saying I had any influence...I'm pretty sure I did not. :)
GOOG wants Cogent to peer. Cogent wants GOOG to pay for transit (from them or someone else to get to Cogent). If you're well peered / multihomed, it's not much of an issue. If you're a single-homed Cogent customer, you should complain to Cogent that they're not providing full IPv6 connectivity.

Hi,
mail from Cogent:
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. <<<<
Mail from Google:
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 <<<<

I just noticed that I am NOT getting IPV6 Google prefixes though Cogent at all. I was told google pulled all of their peering with Cogent? If I bring up a SIT tunnel with HE, I get the prefixes but at horrible speed and latency .. anyone else?
