Yes, the hashrate was taken at the time of the post.
I do not remember in which datacenter I am in, but it is a professional one.

One thing I change from the beginning is the pool : There was some connection problem when using Multipool, so after having a discussion with M. Lee engineer, I move to a chinese one in order to not have connection problem between the hosting in China and the pool in another place. I definitively see an improvement as when the miners had a problem with a US/EU pools, sometime the were not able to get back online easily. After changing pool, I never had this problems anymore. I know the fees are higher, but honestly I do not have to contact the support anymore...
