99.95% uptime is a few hours a year of downtime. Some people lose power almost daily. The thing about exponential / logarithmic distributions is your sense of what is frequent or rare is quite arbitrary and based on your own experiences which are rarely all that representative.

When I lived on country roads miles out of town power outages happened many times a year, occasionally for days. Some I’ve lived in big buildings with buried power lines I’ve never had an outage in years. People in developing economies in some places only have occasional electricity. Is quite hard to say which one is normal.

We have 5-10 outages a year where I live (rapidly growing city in the US), usually 1-3 hours in length but occasionally longer.

The power lines are all above ground and there are lots of trees. Every big storm brings a substantial risk of knocking the power out.

Wow, I did not know that. For me, outages are connected to major disasters.
