The map shows where BTC DSL internet is available and BTC speeds in different areas. When different max speeds are available at different addresses within a hex, color is determined by the fastest speed.
Colored hexagons indicate where BTC services at least one address. Internet service is not necessarily available at every location within a colored hex.
Select a city to show BTC DSL availability in the surrounding area.
Along with DSL, BTC also offers fiber. See BTC Fiber Availability.
Broadband Map's information on BTC DSL availability relies heavily on the December 2025 data from the FCC's Broadband Data Collection program (published May 2026, with FCC revisions through July 2026).
