Crazy how they charge you $350 though, they cost $79 to buy individually (they are probably getting a wholesale discount).
I'm guessing for business accounts they are using the Airfiber which is pretty cool and fast. They can't do 10gbps though, don't think their fibre lines can even handle that much.
Speaking of which, I noticed there's not many Data centers in SF which probably because there isn't much fibre around. My Digital Ocean box in SF is really quick however, even less hops to New Zealand than it is from LA which is weird since the Southern cross cable lands closer to LA.
Others are on the Peninsula and San Jose. There are also several in the Central Valley, which is more seismically stable, though flooding can be a concern.
I'm reporting on 1) what their site claims (10 Mbps residential, 10 Gbps elsewhere), and what actual experiences are (they're delivering more than they promise).
Given that most DSL/Cable options are still a small fraction of that, it's a considerable improvement.
1 Mbps to 10 Mbps, with 100+ Mbps not being unheard of.
Coverage is mostly in the eastern / hipster side of the City: North Beach, downtown, the Haight, Noe, to Bayview. So Sunsetters and Richmondites are SOL. Reports I've heard are that service is fast, reliable, and inexpensive ($35/mo).
