Did any of those maps show the old SBCIS backbone?
You are aware that there is a Tier 1, "Settlement free" group of transit providers running backbones? And there are networks who buy transit from Tier 1 networks, but have other peering arrangements, which are called "Tier 2" networks? And everybody else buys transit from some other transit provider.
No cable company is a Tier 1 network; they don't trade packets ("Settlement free peering"), nor do they sell transit to other providers. They do have their own, internal backbones. It is entirely possible for a Comcast user to run on the Comcast network from coast to coast without traversing a Tier 1 "backbone" provider's network.
