Ever taken the internet offline to a 70 story residual building? I did because when I plugged my laptop in to troubleshoot something the UPS chucked a massive wobbley and decided to reboot.
I once cut the internet for an entire school by plugging in a router.
They had a bunch of misconfigurations in their spanning tree and loop detection systems, and detected the router as a loop. That triggered the network to reconfigure itself using a different route, which was invalid, so the whole network went down.
Their IT wasn’t gonna be there for a few days, and I didn’t set up their network or had any access to it, so I think it stayed down for almost a week.
I’ve plugged a standard console cable into an APC UPS. did that twice before I realized what was going on.
APC decided to do a pinout on their serial platforms that gets triggered with a “Cisco” console cable to shut down. What. The. Fuck.
