One data point isn’t a reliable indicator. A digger isn’t the only risk. There are mudslides, water intrusion into conduits, and simple aging of the underground infrastructure.
How long were you without power for? In 9 years in my current house with above ground utilities, I’ve lost power many times but for a combined total of less than 12 hours, I think. The longest stretch was about five or six hours. Most of the other cases, I’ve had power back in minutes or sometimes, a couple of hours.
