Re: Profitable?

it's partly due to the fact that VZ and many other baby bells have extensive fiber backbone networks of their own. Verizon, for example, has a Tier 1 network, which means they have free peering to pretty much any other Tier 1 backbone on the net. Also, they make money charging others for transit over THEIR backbone, which helps cover part of their costs.
