Rapid Unscheduled Disablement (RUD)

noun
A sudden, catastrophic "oops moment" in IT or cybersecurity where a system decides to take an unplanned coffee break—often accompanied by frantic troubleshooting, finger-pointing, and the ritual sacrifice of a weekend to the tech gods. Usually attributed to Murphy's Law, an overconfident patch, or a rogue cable someone swore "wasn't important."
