There was (might still be but I haven't looked since fiber went everywhere where I live) a local provider to me that use microwave links, it was at the time fast as hell compared to creaking ADSL but every time it rained it went south fast, I worked in a shared office building that used it for it's main links and it was a constant thorn in my side, I used to check the rainfall forecast to see if I'd have decent internet at the office!.
