so annoying. people keep trying to add several non-tier-1 providers in there. cogent 174 : no. buys transit from 2914 (NTT america/verio) btn 3491 : no. buys from savvis 3561 i believe ft 5511 : no. buys from sprint 1239 i'm pretty sure i saw some other silly ones in there, too, but i can't remember what they are at this point. the annoying cogent edits are coming from 72.66.2.5 (pool-72-66-2-5.washdc.fios.verizon.net), and they're persistent, so as is the normal case with wikipedia, the most fanatical person wins and the truth is hopefully somewhere near by. hopefully this person will soon tire. for the moment, the list looks mostly or completely correct. to underline a point made previously though: Tier-1 is a routing architecture term that doesn't have any useful direct bearing in how best to select a service provider. some of the best service providers in the world are not "tier-1" and some of the worst are ( i won't name members of either camp.). t.

What make a provider a tier 2, versus a tier 1 provider...
Is it possible to determine who a tier 2 (i.e. Cogent) leases fiber from?
It has absolutely nothing to do with fiber.

As of this exact moment that I'm posting, that article is actually reasonably accurate. Of course I'm sure in 5 minutes 100 people will be updating it to include their favorite not-really-a-tier-1 carrier. :)
Someone added Cogent as a Tier 1, and there are others missing so I'd ignore the "who" is a tier 1 portion.
