so cogent has no routes to some amount of v6? ie no routes to some prefixes? /kc On Mon, May 15, 2017 at 07:56:14PM -0700, Large Hadron Collider said:
My terminology of tiers are:
Tier 1 - is in few or no major disputes, has no transit, and is able to access over three nines percent of the internet
Tier 2 - as Tier 1, but has transit.
Cogent is neither on v6, and I have no clue about v4.
HE is probably Tier 2 on v4, and is Tier 1 on v6.

Nowadays, I'm hearing this less and less, but it's not completely gone. Putting aside the question of their importance, there is a small number of ISPs that do no pay for transit. If you don't call them Tier 1, what do you call them? Transit Free Providers (TFPs)?
I think the broader and more relevant question is -- Does it matter who pays who ? Why name an irrelevant characteristic?
Cogent may not buy transit but i would not purchase their service since they fail to have full internet reach (google and HE)
And xyz incumbent may have a poor network, but they may get free peering or may get paid-peering because of their incumbent / monopoly status... that is not a reason for me to purchase from them or think they are an elite tier 1.
The dynamica of the day are more around reach and quality, not some legacy measure of how market-failure facilitate anti-social behavior
