I recently moved to a fairly rural area in the midst of them setting up fiber throughout the area. For some reason, the ISP is something like halfway across the country from me. I asked them to setup port forwarding; the first few tech support people I talked to didn't even know what that is. Eventually they relayed the question to an engineer who was familiar with the concept but still had a lot of irrelevant questions, many of which were about the operating system I used. It was ... Frustrating.

I did finally get port forwarding, but it took literally a month and a half, figuratively a million calls, and ten to twenty of their staff over at least three departments. I'm happy now, though.

Edit: sorry about the initially irrelevant and probably boring post. I accidentally pressed post prematurely.

As someone who WORKED for a rural dial-up ISP. We ran our whole data center ON Debian... because we were poor 😭
