Availability of fiber internet, regardless of provider, is shown in the map. Change between a map of the max fiber speeds and a map of the number of fiber providers using the buttons at the bottom of the map.
Fiber internet sends data as pulses of light through thin glass fibers. It's typically the fastest and most consistent option. Download speeds of 1 to 5+ Gbps are common. Upload speeds often match download speeds, and latency is low.
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.
The map allows zooming out to view fiber internet availability and speeds at the national level. However, the map works best when zoomed in, exploring fiber providers and speeds 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.
Fiber availability data comes primarily from the FCC's Broadband Data Collection program, representing ISPs' availability as of December 2025 (published May 2026, with FCC revisions through July 2026).
