What is the "Switch superNAP 9" building on Warm Springs and Jones in Las vegas? It terrifies me just looking at it!?

I read on Google that it is a data center, but I am skeptical and very uneasy with this. I go most places by bus, so I haven't seen anything like this before. I am in my friends car and we drive by this enourmosly long building, quite frankly, looks like a prison. Each dorm looking section has a big vent with bright red lights illuminating it. Then, to make it a little more prison-like, in the middle of this incredibly long and ominous building is a watchtower. The unusually high fence around this compound is heavily laden with barbed wire as well as huge sharp spikes which are pointed both outward and inward. It's obvious, whoever built this monster doesn't want anyone coming in of going out without their consent and knowledge... EVER. Then there is the name.... "SWITCH SUPERNAP 9". I MEAN, AM I THE ONLY ONE WHO SEES SOMETHING UNUSUALLY ALARMING HERE?

It also has it's own substation so is taking a lot of power, and the size of gas main entering it would heat a large hospital. Entrance screams government level security, and the back entrance says "Restricted area" - and also the housing estate behind it - nobody has their own mailboxes. It's like a locker in the middle of each street. Windows are weird too. Closest house may not be a house at all. I wouldn't be all surprised if what you are seeing is the ventilation stacks for many floors below the surface, and we all know where that is going. Could easily extend under the housing estate too. Small telecoms tower on it, but loads of internet junctions all around it covered in concrete - This is very well plugged in!
