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

Zoom out to view Sparklight Cable availability and speeds at the national level. However, the map works best when zoomed in, exploring Sparklight Cable 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 Sparklight cable 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).
