"uniquely Canadian"? Hardly.
Beaver at the confluence of James Creek and the North Fork of Big River (bottom of Seven Mile Hill on Hwy 20, between Fort Bragg and Willits in Mendocino County, CA) took out the telephone line[0] into Fort Bragg in the late '80s, effectively destroying all communications in or out for a week or so. The town now has functional redundant lines.
