    Broadband Map's availability estimates are based on the census boundaries of San Francisco. Speed metrics capture internet providers' maximum advertised speeds. Both may be overoptimistic.

    Data Sourcing

    Broadband Map's listings of business internet providers in San Francisco rely primarily on the November 2025 release from the FCC's Broadband Data Collection program (representing San Francisco ISPs' availability as of June 2025).
