Yes, (power outage though not specifically internet) however that was years ago. I happily live near a bunch on emergency services so power outages never last longer than a few minutes.
Downside- sirens all the time.
Upside- every time someone makes the corny joke "they're coming after you" I get to respond "Yep, because nice guys finish last"
I've had one internet outage, but than was right after they installed internet in my area (they literally installed it right before I planned on moving to the area.) Hasn't happened since, and that was over a year. I figure it was simply something needed a finishing touch or whatever. Didn't last long, and didn't happen while on cam.
