A new website was released by the The National Telecommunications and Information Administration and the Federal Communications Commission to show broadband connectivity across the US. Surprisingly, the web map documents how much of the US is not broadband connected. The map was constructed from approximately 25 million documents that outline connection data across the country.
The areas that have the best connection to the broadband web are the Eastern Seaboard, Pacific Northwest, Bay Area, Chicago and surrounding areas, and Southland. Much of the Mountain West and Southwest (including large parts of Northern California are large disconnected spaces.
Web designers and developers can connect to the map data through an API.
