If you’ve ever wondered just where the fiber conduits that carry our Internet traffic run, wonder no more. Researchers have created a map. Four years in the making, the map, sourced in part from public records, shows the long-haul fiber that carries Internet data around the country. Additionally, locations where multiple cables connect are shown. This kind of map has never existed before. Not much is known about “today’s physical Internet infrastructure,” the researchers say. So they delved in and, through a collection of Tier-1 ISP and cable company maps combined with public records, started to construct a map of the long-haul fiber network (PDF).
