I was working in the web interface of one of our appliances at work just before lunch. One of my coworkers (with whom I share admin duties of this appliance) set his computer to shut down then left to pick up some food. Suddenly I noticed the appliance was unresponsive! I was getting site not found errors, and I couldn't even SSH into the machine. I look at my coworkers computer and realize it's still running, but the last command he ran was a shutdown in a remote shell...
