Rushed to office at 6am before important process was about to run that needed that host.
Plugged in keyboard+monitor, dead screen, nothing.
Physically power-cycled server.
Stood in front of monitor+keyboard. It occurred to me it was taking longer than expected to show POST screen. About that time, I got a page saying $ACTUALHOSTNAME is down.
Walk around to the back of the racks. The monitor cable had come detached from the cable extender that I plugged into the server. I had never plugged the monitor in at all, just the extension.
The server wasn't down in the first place, it just lost a virtual interface, which I was paged for, and stupidly tested that virtual interface instead of the REAL name/IP.
And then I raced to the office just so that I could cause an outage.
Usual checks to access $HOSTNAME failed
