Broadband Map's availability estimates are based on the census boundaries of Atherton. Speed metrics capture internet providers' maximum advertised speeds. Both may be overoptimistic.
The map allows zooming out to view internet availability and speeds outside of Atherton, CA. 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 Atherton, and local variations will be smoothed over.
Broadband Map's listings of internet providers in Atherton rely primarily on data from the FCC's Broadband Data Collection program representing Atherton ISPs' availability as of June 2026 (published October 2026).
