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.
Fiber availability data comes from the May 2026 release of the FCC's Broadband Data Collection program (representing ISPs' availability as of December 2025).
