What make a provider a tier 2, versus a tier 1 provider...
This has been answered by Richard, but to put my two cents in - you shouldn't care. There is very little correlation between performance, support quality, or footprint and "tier status". That's one reason folks like Vijay Gill have been trying to get people to use more precise terms like "Settlement Free Interconnection" (e.g. "Verizon Business is completely SFI") rather than "Tier 1". Also, many companies (or their sales staffs) aren't truthful about their status, or make misrepresentations about what their status means. The list of extremely large and important non-Tier 1 carriers is long - look at DTAG, for instance, or Singtel.
Is it possible to determine who a tier 2 (i.e. Cogent) leases fiber from?

Cogent, for example, is a Tier 2, but that's not a good reason to either buy or not buy transit from them. There ARE good reasons (both ways) but that's not one of them. Daniel Golding
