The California Public Utilities Commission (CPUC) collects broadband availability data once a year and displays it on the California Interactive Broadband Map to provide Californians a means to look up broadband speeds and service providers in their area. The Map also provides information on funding eligibility by location for California Advanced Services Fund Infrastructure Account applicants. Equally important, the data inform public policies looking to bridge the digital divide in California.
