Data centers go underground.
The main entrance to InfoBunker's underground facility is a four-inch-thick, 4.5-ton main blast lock. It serves both as a secured entrance and as a very heavy-duty person-trap. Visitors must pass through two doors that are interlocked. One will not open before the other is closed and sealed.
