Was relocating a $10k piece of networking hardware and dropped it into another 10k VM server. Server was fine, network hardware was not. It was during a project that was a real mess, thought it was a stupid mistake though.
We were able to work around it, though we did lose the contract we were trying to make. Honestly though given how rushed and panicked that whole three months was though, we were lucky nobody suffered anything worse. Real shitshow.
Iirc literally the nuclear launch systems? I’ll see if I can find the article.
Edit: not anymore, but as recent as about 2019ish. Can’t imagine they’re the only ancient infrastructure still using this level of technology though. https://www.nytimes.com/2019/10/24/us/nuclear-weapons-floppy-disks.html
