The note about opening the door resonates with me. On two different occasions I've come across IT people scratching their heads about how to get into the server closet. On the first occasion the guy with the key was at a BBQ and in no shape to drive. I opened it with a library card. On the second, the Kisi server controlling the door had crashed (guess where the server was). I opened it with a butter knife. On both occasions I opened the door quicker than my wife can find her keys in her purse. Lesson 1) Secure your server room against physical attacks Lesson 2) As you secure your server room make sure you make an emergency plan for how to get in to your newly secured server room.
