Here is mine.

The admins could connect to their machines, but not to any user machine.

It was winter and we had some heating issues, so I made a script "warmup_the_office.sh" that was meant to launch a "while(true){}" on each core of each PC of the office, but instead launched itself indefinitely on each and all reachable machines, exhausting all pids and preventing distant logging. We had to reboot everything by hand, after some nice warmup.

What a gloriously dumb idea. If I had that sort of access, I'd probably try something similar, and probably get the same results.

Did you admit what happened, or was there a "mysterious widespread network failure"?

The mystery didn't last long, and no problem to admit it, I maybe even contacted them. I guess they put safeguards after that, but I didn't try again to check ;)
