I'm starting to think about it too, but it's kinda difficult finding someone to host miners in France.
On the other hand, I know a couple of people working for the national power company and they get a 90% reduction on their electricity bill.
Now I just have find a nice 19" rack and convince one of them to make some space in their garage
For some people it could mean the difference between continuing to support the kano pool or shutting down unless they can find a good hosting site. Keep in mind when you are searching for a host site it does not have to be in the same region or even the same country you are in. I'm in the US but the first data center that hosted my miners was in China!
I currently have a bunch of S7s at Toomim Brothers (
http://toom.im/) and I could not be happier with them. Jonathan and his brother are quick to act, knowledgeable, conscientious, and are great communicators. (think USA versions of kano and -ck
)
I know we have some here that host at Oregon Mines (
https://www.oregonmines.com/) and I hear that SideHack is full right now. I have the last of my S5s in a data center in Sweden (not recommended).
The cheapest place I know of is Great North Data (
http://www.greatnorthdata.com/). I seriously tried to send a bunch of S5s to them but at the last second they decided that they would only take a new client if they had at least 30KW of hardware. My S5s at the time were only 10KW worth. I have not heard if they still have this policy or not.
