sorry, i have to admit that we made a mistake and donot evaluate very well on the power reliability of the current data center we use,  most offline issue comes from the fact that too much equipment are allowed to run on the electricity net and lead to the automatically power off because over-load, we will transfer 1/3 of our miner in this data center to our new data center within several days  and low the host fee in this data center  after this round, meanwhile, we are talking with lketc to rent some place on their professional farm to provide host service,  where not only can support as much as  20,000 unit dragon, but also with very professional design and very stable power supply, we almost make the final deal with them,  if everything going well, we should make the final agreement within this week.
