Map Scale

The map allows zooming out to view internet availability and speeds outside of Petersburg, AK. However, map hexagons grow to accommodate larger views. Since the availability or speed of service at a single address can dictate the color of its hexagon, national-scale views won’t show the same level of detail as the view of Petersburg, and local variations will be smoothed over.

Data Sourcing

Broadband Map's listings of internet providers in Petersburg rely primarily on data from the FCC's Broadband Data Collection program representing Petersburg ISPs' availability as of December 2025 (published May 2026, with FCC revisions through July 2026).
