The map shows where ATC fiber internet is available and ATC 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 ATC services at least one address. Internet service is not necessarily available at every location within a colored hex.
Select a city to show ATC Fiber availability in the surrounding area.
Along with fiber, ATC also offers cable. See ATC Cable Availability.
Zoom out to view ATC Fiber availability and speeds at the national level. However, the map works best when zoomed in, exploring ATC Fiber availability in specific regions.
The availability or speed of service at a single address can dictate the color of the hexagon the address falls within. Accordingly, national-scale views with large hexagons will smooth over local variations in internet availability and speeds.
Broadband Map's information on ATC fiber 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).
