These guys have dark fiber right in front of my neighborhood. They service cell sites for Dish Network near me as well. It's interesting to look through their services. For example, you can get fiber service with layer 2, where you're responsible for adding your IP stack over top of it. Or you can buy at layer 3, where Segra is already running a stack, and establish mesh connectivity. So if a fiber is cut, you'll get another working path. Build your network over the top.

Pretty interesting to understand what's available.
