I toured Layer42's Mountain View facility and it looked pretty good. Don't remember exactly what the power prices were, but it was comparable to Sacramento. I stuck with Sacramento since it was closer.
huh. I had a bunch of stuff in heraklesdata in sacramento. They quoted 150% of the 20a 120v circuit price for 30a 208v. I told the guy in the rack next to me (who ended up doing better than I did) and he wanted me to quit explaining power to the salesguys; this guy's theory is that one of the bizdev folks didn't know how to calculate power from amps and volts.
It's pretty funny; here in santa clara, people charge about twice (per amp) for 208v as 120v. thus, I end up just getting a whole bunch of 20a 120v circuits. It's silly, but eh, watts are what I actually want.
(208v is slightly more efficient; but an amp of 208v is, well, 208 watts, and two amps of 120v is 240 watts... 208v is not /that/ much more efficient.)
