HE in Fremont is a very special place. I have about 10 racks there. They're cheap and bandwidth is free, the support is awesome, but it's a ghetto, to put it simply. Or a hippie camp. The racks are telecom, not computer ones (which means that they're shallow and narrow, 30" long server prevents the back door from closing). The power is not redundant and only 15A per rack tops (extra amps are ridiculously expensive).

But for a frugal startup it's perfect - cheap, good connectivity, awesome support, easy access. Not very reliable, right, but you don't have many users, don't ya? :-)
