Availability of DSL internet, regardless of provider, is shown in the map. Change between a map of the max DSL speeds and a map of the number of DSL providers using the buttons at the bottom of the map.
DSL (Digital Subscriber Line) delivers internet over existing telephone lines:
DSL is often available in rural areas where cable and fiber aren't options, though speeds may be slower.
Availability is reported at the level of hexagons rather than addresses. Not every address is necessarily serviced within a hexagon where a provider reports availability.
DSL availability data comes from the May 2026 release of the FCC's Broadband Data Collection program (representing ISPs' availability as of December 2025).
