Most major ISPs in San Francisco are built on oversold, shared infrastructure — which can mean slowdowns when the network is busy, unpredictable bills, and support lines that leave you on hold. Sail owns and manages its own network, charges flat rates with no hidden fees and provides a responsive, local support team.
