Outages Caused by Squirrels:

“I don’t think paralysis [of the electrical grid] is more likely by cyberattack than by natural disaster. And frankly the number-one threat experienced to date by the US electrical grid is squirrels.” – John C. Inglis, Former Deputy Director, National Security Agency 2015.07.09

As told to The Washington Post, The American Public Power Association, a group representing municipal electric utilities, says that squirrels are the most frequent cause of power outages in the U.S., although it notes that squirrel-induced outages typically affect fewer people than outages caused by storms. “Squirrels remain the biggest wildlife nemesis because of their sheer numbers and smarts,” the story concluded. See article.

A recent incident in the Cyber Squirrel database happened on January 2 in Wagoner, Oklahoma. A squirrel touched grounded wire at an electric substation, knocking out power for a portion of the town for five hours.
