Re: Irony? said by espaeth:Unless you have service from Qwest, Frontier, CentryLink (formerly CentryTel & Embarq), Charter, RCN, Comcast, TWC, Cablevision, Cox, etc. None of those carriers rely on Verizon or ATT backhaul for their upstream connectivity -- they push traffic to carriers like Level(3), GlobalCrossing, Qwest, Telia, Cogent, Savvis, PCCW/BTN, etc. Which, often times, switches over to ATT or Verizon backend at some point to get to it's destination. Do some trace-routes to various sites. I am not on ATT or Verizon but I see their routers come up a lot in tracerts. Have you even seen the sizing charts that compare backend sizes? Level 3, GC, Cog, etc. are like specs compared to the spider-web-like appearance of ATT and Verizon on those charts.

They aren't centric to any kind of traffic pattern, and that shows quite well in metrics like the Knodes index. See: »www.fixedorbit.com/metrics.htm

ATT and Verizon are stretched very far, and very thin. They connect a lot of edge customers, but really don't have the core bandwidth to support the same amount of transit volume as a Level(3) or Global Crossing. When Comcast ended their contracts with ATT in 2006/2007, they cut ATT's US backbone loading levels by over 50%.
You also won't find any major US data centers using ATT or Verizon network connectivity.

ATT / Verizon do quite a bit of business with end-user attachment, from residential DSL subscribers all the way up to Fortune 500 enterprises. For core backbone transit, however, they priced themselves out of the game years ago. | |
