"What other hidden systems are out there, where if they went down, everyone in the world would quickly notice? How many of these systems are patchwork quilts, and how many are run by one institution?"

Power grids for electricity. In Canada and the U.S. many of them are connected by wire to each other due to power supply arrangements between the countries. Bad weather of all kinds can create outages not only for the originating local area but also others far away from the action.

Most of these grids are owned by local, government-funded concerns who have near monopoly control of the resource in their geographic area.
