Over a million people lost power in Texas just about one week ago, an issue that continued to impact hundreds of thousands of people days after the event. Hundreds of thousands lost power for multiple days last winter as well following another cold snap. Those are two events I can recall by memory - one because it's so recent, the other because I was personally impacted by it.
Do other states regularly have multi-day outages that impacts hundreds of thousands of people? I know California has at times with wildfires, but other than that? Are these issues below the line for being considered "systemic"? I'm actually asking, not refuting using question marks.
