The map shows where CenturyLink DSL internet is available and CenturyLink 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 CenturyLink services at least one address. Internet service is not necessarily available at every location within a colored hex.
Select a city to show CenturyLink DSL availability in the surrounding area.
Along with DSL, CenturyLink also offers fiber. See CenturyLink Fiber Availability.
Broadband Map's information on CenturyLink 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).
