|Click for a better view of the sign.|
I think I finally found the answer to that question recently while working at a client site. This door was just a simple door in a wall in the basement of the building. Nothing special about it, until I noticed the sign. I was afraid to open the door for fear that the bits and bytes might get out and the client would be mad about losing their data due to my negligence.
Well, now I can honestly answer them when they ask me where their data is.
