I worked on multi-million dollar airplanes. If a pilot called me with an issue and hadn't rebooted the plane (on the ground), I wouldn't even talk to them. Rebooting isn't always a bad solution to technology.

In maintenance, sometimes the dumb solution is the best. The servers that ran amazon.com had a memory leak and were subsequently restarted. This hack continues for years because it was the most cost-effective thing to do.

Put another way, if they didn’t turn it off and on again, I would think less of them because that’s the first thing you should always do unless you know better

Powercycling is a designed method to bailout Cisco routers. If you botch a configuration command and lose connection, you can have someone powercycle it to restore you last good configuration. Its not just a joke it really works more often than I'd like to admit.

Amateur hour. Everyone knows professionals say "power cycling" instead to make it sound complicated.
