I once toured a similar facility, complete with hand scanners and airlock-style double doors throughout the facility. After going through countless layers of security we reached the deepest, most secure section of the data center where the most sensitive servers were housed. On the opposite side of the room there was a fire escape door propped wide open, leading straight outside into the sunlight.

Our tour guide, who was an investor in the facility, explained that the employees really hated going through all of those scanners and double doors, so in the morning they just prop the back door open. If a customer or potential customer comes for a tour, they make sure to close the door.

The other highlight of that visit was the generator room, complete with some truly massive diesel storage tanks. Our guide (the investor) proudly explained that they could run the facility for several days in the event of a natural disaster which knocked out power to the facility. Out of curiosity, I knocked on the side of one of the tanks, only to be greeted with a hollow echo sound. The investor then explained that the tanks are mostly empty, but they'd fill them up if they thought a natural disaster could occur.
