Events and circumstances in which squirrels have caused major power outages
Electrical disruptions caused by squirrels are common and widespread, and can involve the disruption of power grids. It has been hypothesized that the threat to the internet, infrastructure and services posed by squirrels may exceed that posed by cyber-attacks.[1] Although many commentators have highlighted humorous aspects of the concern, squirrels have proven consistently able to cripple power grids in many countries,[2] and the danger posed to the electrical grid from squirrels is ongoing and significant.[3][4] This has led to tabulations and maps compiled of the relevant data.[5]
