There have also been fatal aviation accidents where there's a problem with a common system (a dip in the power supply or hydraulic pressure, or a problem with a critical sensor) and dozens of systems sound alarms at the same time [1].
And for a technology example, a database server disappearing might raise a single alarm, but the applications that rely on that database might raise countless alarms as attempts to connect fail over and over again.
