Imagine if humans decided to hibernate en masse on Earth (maybe because of an ice age or fallout or something). We'd almost certainly set up alarms so if one hibernation center were damaged or destroyed another one nearby would thaw out some people (or machines) to go investigate.

Same thing would make sense on larger scales.
