Looks like a gpu farm, all the worker hash rates fall in line with what you would expect of a rig.
Lolz so 250+ rigs?
Once you consider there a warehouses filled with gpu racks, it starts to get crazy.
Those owners sometimes open a couple of locations and they probably split up the workers to various address for whatever reason, really its impossible to say how large they are. If I worked at a location like that I would probably siphon off a few racks to mine at my own address and blame it on downtime ;P

Janssens himself made a fortune as a Bitcoin miner back in the currencys early days. When the price of Bitcoin took off in 2013, he was three years ahead of the curve.
Incidentally, he was already a PrivateFly customer, but said when the company turned to Bitcoin, he was the first in line.
