I'll chime in for Teslawatt (previously cerad.net) as the owner wanted a review and I'll give my 2c.

I've been using their services since last August. I have 6 GPU rigs with them, totaling 24 1080 TIs. I met the owner last summer while I was in search of a place to put the rigs since paying $0.47 per kw in southern california electric rates were killing the profits, and the added garage heat was not helping. I was very skeptical since they were just starting out when I first contacted them and putting thousands dollars worth of equipment in the hands of a stranger was not the best case scenario, but being desperate to find a place to put my rigs, I took a chance.

I had pretty good service since then, which has been improving constantly. I have remote access to rigs via VPN, and they have an on-site guy who is very responsive to requests (in the range of minutes to couple hours), even weekends. I'd say the on-site guy is knowledgeable, as he helped me debug issues with BIOS, windows and unresponsive GPUs. I think I've seen two major outages where internet connection was lost, but downtime was never longer than couple hours, and this is during 8 month period. Rest of the time, the rigs have been pretty care-free and stable. No hardware fault during this time either.

I'm about to go there a second time to install another set of GPU rigs within 2 weeks, I dread the driving, but I'm glad to get rid of the accumulating rigs in my garage.

I have nothing but good things to say about this place and the owner. I know it's always a question mark when you see the horror stories of scam host companies, do your research, check the references, don't take anyone's word, and go see the place if you can.
