I spent many years working building and maintaining fiber networks, and I can unequivocally tell you that the answer to this is maybe. Normally you can treat city fiber just as any other ISP. A lot of them have different rules and different thresholds on what they allow and what they do not allow. Fiber networks are extremely expensive to build. So while you definitely need to protect the multi-million dollar investment you've made, depending on how you've built it it can be a little tricky to police what everyone is doing.

What's interesting is just because you are not receiving notice of a DMCA infraction, that does not mean that your ISP has not received a notice. There is this idea that if you are not set up for it it is difficult to track out what account held what IP 30 days prior or 60 days prior. That is kind of a BS excuse, but I have been at companies that did not have logging because they did not want to have logging.

We did collect email notices and pass them around though weekly to see who could find the most absurd DMCA takedown. So I will say, if you were pirating some weird ass mommy fetish furry porn everyone in that call center knows it and is laughing about it.
