Why internet availability matters so much in San Francisco
San Francisco has multiple broadband networks, but provider availability can change between neighborhoods, streets, apartment buildings and individual addresses.
Fiber availability varies

Apartment buildings matter
San Francisco has a large number of apartments, condos and multi-unit buildings. Building infrastructure and provider agreements can affect which internet options are available.
Remote work & connected homes
San Francisco households may have demanding internet needs, including remote work, streaming, gaming, cloud applications and connected devices. Faster plans can be useful for larger households.
Local availability
San Francisco internet by neighborhood and area
