Apologies for the lack of detail, I wasn't present in the room but did see the effects. One Thursday, there was a lot of grumbling at the end of the day when an unfortunate IT engineer took down the main data centre by accidentally hitting the big red button, causing people to lose unsaved work. The following Monday morning, the same thing happened again, with similar grumbles.
I later learned that the second incident happened *because* the engineer in question had fitted the big red button with a cover. They were proudly showing it off to their boss by sharply hitting said cover, which hadn't been properly fitted and gave way just enough to trigger the button again.
