Bill Cheswick of Lumeta has put together an updated map for CIO Magazine, showing who owns the Internet’s backbone networks. Not surprisingly, Verizon, AT&T, and Level 3 dominate.
As I’ve mentioned before, this is the less-discussed other side of the network neutrality debate; whether backbone providers can impose a tiered Internet on content and application providers, separate from what residential broadband providers might do with their customers. Although in the case of Verizon and AT&T, those could be the same company. (Thanks to Greg Staple)
