Alt tabbed once too many times, clicked drop database and yes. Deleted the live authentication DB for America's Army: Operation video game.
Missed the word "add" in "switchport vlan add" on a switch, overwriting the list instead of appending to it. Took out the only connection between two datacenters we were in the process of migrating between. Took me 14 minutes to run to the datacenter, plug in a console cable and fix it.
Similar to your #2, but less serious, I once wrote a script to power down virtual machines for a data center move. It was a nice piece of work too, grouping them in batches, sending shutdown commands to the guest OS, falling back to forcing a power off through the hypervisor after a configurable timeout...
I don't recall the specifics of the problem or the virtual infrastructure I was working with, but in short I didn't have sanity checks on what was being shut down. Ended up force shutting off the hypervisor/virtual infrastructure management system.
Added an extra few hours the move with that.
I can absolutely see that happening in vsphere.
