Map of North American Internet

The folks over at the CIO blog have released a map showing the North American internet backbone. It includes every one of the 130,000+ registered routers, and is color coded by company.

In order to build this map Ches fired off 300,000 messages to various points on the Internet and mapped how they got there, recording the address of every router his packets passed. He also had to figure out a way to isolate routers in North America. The map is not perfect – he probably missed a few points and maybe double counted a couple more – but for all intents and purposes this is what the North American Internet looks like.
