San Francisco is an interesting case (and I say this as an SF native). The city government is so unfathomably dysfunctional in large part due to London Breed (the current mayor) bringing cronyism back as fast as she can.
Parts of the city are covered by MonkeyBrainz (microwave p2p), parts by Webpass (fiber), and most of the city is covered by Comcast (cable) or PacBell/SBC/AT&T (DSL and adjacent). Up until Sonic started rolling out 1 Gbps fiber a few years ago all I could get at my last place in the city was 3/1 Mbps ADSL or Comcast.
PacBell was always reluctant to build out RTs compared to GTE/Verizon (who has a significantly smaller presence in the Bay Area) so DSL speeds in large chunks of SF were always shit. Even when they did build out RTs the ILECs were never required to resell RT access so speeds remained shit. I'm not entirely sure why AT&T's U-Verse (FTTN, VDSL last mile) was rolled out so slowly but I expect the need for intrusive sidewalk boxes was part of the problem. Sonic got boned because SF's supervisors were/are reluctant to allow micro trenching. For a while there was some buzz about muni fiber but that never got off the ground (and Sonic certainly helped put a few nails in that coffin).
