My partner's father works for AT&T and he has related a story where at least one cell tower went offline because the office was ignoring the NO LINE POWER/BACKUP GEN FUEL LOW warning duo[0] and assumed all was good when the warnings went silent when, in fact, it was now dark. [0]A very rural installation that often experienced power cuts, so they had become numb to alarm 1. Somewhere in the mystical ticket/service system, the schedule to refuel the tower had go awry so it gradually sucked down its fuel over the course of many power interruptions and viola.
