If you are in Santa Monica City proper, Santa Monica has a not-well-known fiber network: http://gismap.santa-monica.org/GISMaps/pdf/smFiberOpticsZoni...
TrueCar uses the city's fiber network to connects between its buildings with dark fiber, get a gigabit cross-connect to its colo in downtown LA, and 500 megabits of nLayer bandwidth to the offices. The service has been fantastic and is cheaper by far than anything else we found.
