I’m not sure how this actually happens, but the University of North Carolina physically “lost” one of their network servers, and after four years, found it fully operational located in a wall. Here is a snippet from the Techweb article explaining the incident:
Try as they might, university administrators couldn’t find the server. Working with Novell Inc., IT workers tracked it down by meticulously following cable until they literally ran into a wall. The server had been mistakenly sealed behind drywall by maintenance workers.
Please tell me this didn’t happen by accident. Now tell me what you think.
