No matter what kind of business I build, I don’t expect to pay transit
unless I am asking you to deliver packets to people who are not already
paying you.

Yes, if I make that request, I may also be paying transit for packets that
go to some or all of the users that are already paying you, but I would
expect in most cases, that is an artifact.

If I have content that your paying customers want and your paying customers
have enough demand for my content that it would fill one or more
interconnection-sized pipes (whatever your standard minimum interconnect
is, be that 1G, 10G, 100G, etc.), then I think it is reasonable to ask
for settlement free peering to reach those customers. If there isn’t
enough demand from your customers to justify that, then there are a few
other possibilities… Exchange points in common and public peering,
I give up on those customers, or, I pay you (or someone else) for transit.

I’m pretty sure in the case of Cogent<->Google the traffic level more than
justifies a reasonable number of PNIs in a diversity of locations.

Depends on how you connect to said transit provider, but yeah, you can
either peer with Google yourself, or, you should be able to expect that
anyone you are paying for transit peers with Google as part of providing
you transit service to “the internet”.

It’s very hard to make a case that “Internet Access” can be sold if that
doesn’t include access to Google.

Sure, it’s their choice, but in so doing, there’s a valid case to be
made that they are not providing the contracted service to their transit

I don’t think anyone is saying “Cogent can’t do this”. I think we are
saying “Cogent’s customers may want to consider their rights and their
contracts with Cogent in this process.”

Yes and no… How many of the Alexa 10, 50, 100, 500, 1000 are hosted
at Joe’s?

I think those numbers are a bit different from Google and like it or not,
there’s meaning to that.
