At a place I worked we had a service that relied on a cron job running a script every hour. One day someone wanted to know where the server was so he could connect an external hard drive to it and copy some files in. Not a single person knew where the server was or even what it's IP address was. Since it had been setup years ago, everyone who had worked on it had since left the company and no one ever documented it. So somewhere either in our office or in one of three public clouds we used was a server happily running a script every hour that no one could locate or stop. We eventually found it when we moved offices and a super old Dell box in a tiny dusty closet was unplugged and the script stopped running. Now I always document the physical locations of services too.
