sorry, we are trying to resolve the issue
and i think we can resolve it soon with our back up power supply
so 1 hours downtime are added and make the total downtime this round to 8+3+1=12 hours

today the downtime is 3 hours, yesterday is 8 hours, so total 11 hours down time(21/8/2014-20/9/2014) in this round, i will compensate the extra part exceed 48 hours

on professional data center, i will compensate any downtime exceed 7.2 hours each month
on standard data center, i will compensate any downtime exceed 48 hours each month
but what i want to point out is that if the downtime are caused by miner itself, it is not calculated
but if the miner have problem within the first month you buy, i will replace one for you
BTW, now the slots of professional data center is only open for S3

they inform me the problem is resolved and the power will restore soon, within half an hour

sorry, the power off again, the good thing is our back up power almost complete, should be work next week
then we will switch to back up power within 5-10 if such situation happen again

sorry for the delay of reply, guys
it is true that our farm is not very stable currently, we are trying to get it better and we have developed a new firmware and will improve on two side
1)will let us adjust the frequency of each hash board, which is useful for the very old dragon which have five blade and need run on 800 or 850 frequency, with old firmware, we canot do that since it has no option to adjust the frequency and thus we canot open remote access to some old dragon like spiccioli's, your miner will online soon with new firmware
2) will have an auto-motitor to check the status of cgminer and if it find cgminer stop it will start it automatically, which is very useful when the power off and restore, as you can see, although we have some powered off issue on simple dc, it usually back up within 1 hour, but with old firmware some miner will not re-start automatically and will stop there for a long time if not started manually,   i have ask our employee to check the status of each miner after power restore , but so many work to check with more than 500 miners in our farm

thanks for the trust, and we are trying to do our best to provide good service. to be honest, it is true that many problems are new for us when building the simple data center and host more than 500 unit miner in one place, it is completely different work as host one or two miner in home. but now, we have resolved most of the problem and learned a lot from that and we have confidence to provide reliable service in future

btw, i will never steal any hash rate from host miner, it is not my way to earn money.

yes, you can do that, just let me know the deal and i will register the miner to the buyer

should be fine now
the totally downtime for some of the miner is almost 24 hours
and if the total downtime in this round exceed 48 hours, i will compensate

sorry, everyone, seems like we really need update our equipment to get the farm become more stable
we have tried to find the solution now
and our back up power and back up fan will online next week
then we will promise that the downtime will never exceed one hour

sorry guys, one electrical pike destroyed all our fans, we have to shut down some miners to keep the temperature, although the temperature has  drop a lot last week, but we have more than 400 miners in our farm, it is no way to keep the temperature without working fan
we have contacted the factory to send new fan today, and will get the miner work after this problem is resolved,
sorry for that, such thing never happen during the last few month, and we only have 2 back up fans

sorry easy2mine, that is only the coincidence that our domain is the same with your forum id, he has no relationship with our website

the fan system in data center have problem and we have to shut down all miner to protect the miner from over-heat， the engineer is already work on this issue，should be resolved soon

the host fee will adjust to 110-135$ per kw from next round

you are right, will be restore within one hour

network problem, resolved after connecting isp

if anyone want to buy s3 quickly, you can buy hosted s3 in my farm and the price is 479$(PSU included ) and switch to your pool within 12 hours, if i was awake, i will give them to you usually within half an hour maybe it is not good to advertise my own website on BM threads, so if you have interest, contact me via PM:)

Pls delete

yes, we have to admit that the profit each miner can produce become less and less, which means that you have to buy a lot of miner to get some profit, the good thing is the price of the miner also become cheap, so you can buy many unit of miner with the same money, but that will lead to too much power usage, it is impossible to host so many miner in home if you want to buy more than 50 unit s3, so host is still the good way, meanwhile on my side, seems i need to adjust the host fee in future to let customs make profit on long run,  the good thing is if the amount of money each miner can make not very much, the reliability of the power supply is not very serious, since i can just deduce the host fee of lost time.
BTW, we will draw a back up power supply within 2 weeks, however, we canot provide UPS to make no power cut time, which means  although we can not promise no power off time, but we can promise that there will be no long time power off time, if the power off longer than 1 hour, we will switch to back up power supply

0.66 btc is about 386$ , and psu is about 40$, set up fee 15$, so that is about 441$, and if i sold my running one to you today, even i place a new order at 0.66btc, the bitmain can only ship the new one out on Aug 12 and arrive in my DC on Aug 14, so i will lose about 5 days earning, which value 0.01*5=0.05 btc or 29$, so the total price is about 470$
and i only have 9$ profit, if they delay for one day, i will no profit at all.

anyway, it is not the meaning of my question, can you give the profit of 180 day?
