When I worked for a small business MSP, my boss had an off hours call about an issue, walked the guy through rebooting their server. He was monitoring the uptime so he saw it go off. Then he told them to turn it back on. The guy said he did, but my boss never saw it come back online. He asked him if it was lit up, the guy said yes. He said “are you sure”, and the guy, annoyed, said “yes! I see lights”. Waited a bit longer and it never came online. He called another person at the business to check, and they too confirmed that it was lit up. So he drove 35 minutes to go to their office, walked in their network closet and hit the power button, and magically it turned on. They were seeing the lights on the router, an entirely different machine sitting on top of the server and thought it was on. The issue was fixed by the reboot alone and my boss drove home very very annoyed.
