So the server went down unexpectedly today. This was very unnerving because we thought it had somehow been seized or something terrible like that. Fortunately it was just some kind of glitch and we were able to reboot. Everything has been backed up and is totally current, but we are not going to turn the site back on for a couple of days while we work out a way to prevent such problems. We are terribly sorry for this inconvenience, but we want to provide the best service possible, and random outages just aren't going to cut it. We know it must be terribly frustrating, but we are taking the better-safe-than-sorry approach and we hope you understand.
Geez. Spent an hour troubleshooting my TOR.
So, yeah, a friend and I had $7,500 lined up for two 6-GPU mining systems but we backed off when we had a closer look at the difficulty variance. It just didn't appear to be financially sound for longer than a month or two. Best case scenario we would have broke even. (According to a worst case scenario difficulty chart. If that makes sense.)
