Realistically, beyond these "jinxes", there are places where electrical service is far more reliable than in others. In certain areas of the city you have lots of redundancy and switches so that faults can be isolated and routed around. Places where you can have a bunch of separate power line cuts where nobody loses electricity or where there is no way for more than a few buildings to lose power without lots of electrical faults in the area. If you know what you're looking for, you can find lots of automated switches on the electrical lines within the city. By contrast, there are places, especially as you get further from major cities, where if a single tree falls on a power line running for miles through wooded or tree lined streets, everybody in that area is without power.
