Is XO Communications a Tier 1 ISP? ... Any help here? Thanks as always.
Having written a good portion of that page, in the interest of full disclosure, I would like to point out some of the comments made while I was editing (and re-editing) the page. I do not _know_ XO has settlement agreements with Sprint & L3. Such contracts are covered by NDA, so (supposedly) only certain people inside Sprint, L3, and XO know whether XO is paying settlements. That said, does it matter? Settlement-Based may actually have a slight benefit over Settlement Free, as links which generate revenue may get upgraded faster than links which do not. Perhaps more importantly, does Transit Free matter? A network which has two diverse transit providers is orders of magnitude less likely to be affected by bifurcation events than transit free networks. Not to mention many non-transit free networks have better quality and service, IMHO, than some transit free networks. But hey, your money, your bits, so your decision. You want to buy from XO because they are Transit Free, or not buy from them because they are not Tier One, so be it. What's that line about competitors and encouragement... ? =) -- TTFN, patrick
