The map shows where CNSNext fiber internet is available and CNSNext 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 CNSNext services at least one address. Internet service is not necessarily available at every location within a colored hex.

Along with fiber, CNSNext also offers cable. See CNSNext Cable Availability.
Zoom out to view CNSNext Fiber availability and speeds at the national level. However, the map works best when zoomed in, exploring CNSNext 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 CNSNext fiber availability relies heavily on the June 2026 data from the FCC's Broadband Data Collection program (published October 2026).
