The backbone is now owned by the telcos
No its not. Large portions of the fiber plant are privately owned, as well as the companies that light it not being ATT or a BabyBell. Many naps are privately held and provide public switch fabrics anyone can plug into.

If you start block people's traffic you are probably in violation of your peering arrangement with another provider... Tier1 providers depends on their peering and transit arrangements to be able to deliver 'internet access' to their transit customers. Their peering is for resiliency and reach. > In addition to that, they don't need to own the backbone (or even the > last mile).

It doesn't make business sense for backbone providers(tier 1 networks), because it would probably subject them to de-peering. It doesn't make sense to ISP's, because we like all of our customers and I don't want to lose customers to my competition because they can't tinker with the latest 'intarweb' fad. Both ISP's and Backbone providers already have fair competition to deal with and host of service providers with ambitions of being tier 1 networks working their way up the food chain. The only place where this type of anti-competitive practice makes any business sense is if you already have a natural monopoly to work with. Like the last mile. > Ruben -- NYCwireless - http://www.nycwireless.net/ Un/Subscribe: http://lists.nycwireless.net/mailman/listinfo/nycwireless/ Archives: http://lists.nycwireless.net/pipermail/nycwireless/
