Broadband Map's availability estimates are based on the census boundaries
of San Jose. Speed metrics capture internet providers' maximum advertised speeds. Both may be overoptimistic .
Data Sourcing
Broadband Map's listings of business internet providers in San Jose rely primarily on the May 2026 release from the FCC's Broadband Data Collection program (representing San Jose ISPs' availability as of December 2025).
