Kusanagi is quick with finding news, so I am not sorry that I will reference him again. The article from 'The Washington post' explains how squirrels can trigger large power outages. Squirrels need protection from the elements, and therein lies the cause. To find shelter, they try to squeeze into all kinds of nooks and crannies, which are often electrically conductive—all it takes is a little moisture, and boom! A circuit goes down. In a way, these creatures are ‘shorting the circuits.' I don’t want to whistle in the USSR, but what do you want? That’s just how things are.
