The following description is provided by the FCC: This map displays where Internet services are available across the United States, as reported by Internet Service Providers (ISPs) to the FCC. The map will be updated continuously to improve its accuracy through a combination of FCC verification efforts, new data from Internet providers, updates to the location data, and—importantly—information from the public. ISPs offering broadband Internet to fixed locations (such as homes and small businesses) must report where they offer service on a location-by-location basis - the same location points you see on the map - which come from the Fabric.
