Rented for 6 hours yesterday. No issues. Got the hash rate I expected.

Rented a rig for 2 hours. It went offline 10 minutes after signing up. At this point, I don't expect it to come back online.

Edit: Lobo13 sent me a PM today and although we're not sure why the server was offline, he offered to refund the lease rate. I've confirmed receipt of the refund in my wallet.

(thanks for the quick turnaround, lobo!)
