Can anyone explain to me why end users find it so important to label carriers as "Tier 1" or "Tier 2"? The prevailing theory in the heads of prospective customers is that a "Tier 1" is somehow inherently better than a "Tier 2" (or lower), even though they don't quite understand the concepts behind why the "Tier" designation even exist(s/ed). These labels, at least to me, are no longer very relevant in today's internet world. In fact, would anyone agree that being a "Tier 1", as Cogent believes themselves to be, leaves that network in a very painful position when things like their frequent peering disputes happen? For an NSP, it's obviously a "good thing" to be SFI-only, as in theory, it _should_ lower your costs. YMMV, as mentioned in a previous thread. However, what does it really matter to an end-user, especially if they are biased towards using "Tier 1" networks only? Why does a network who purchases transit give the impression to end users that that network's internet genitalia is somehow smaller than, say, Verizon or AT&T? I can see merit in touting the size and coverage of the actual network, but it's always been my understanding that this is not the true definition of the tiered system. -evt
