It’s country-wide, except in the very few areas where municipal broadband or community-local ISPs have stepped in and run their own fiber. There’s a fiber loop a hundred feet away that’s restricted to businesses, but it still scares Comcast (because it’s a fiber run by one of those local ISPs) enough that my price for a symmetric is half what it would be on the other side of town.
