If you can't get municipal fiber where you live in Longmont (I'm a resident; hi!), you should most likely be complaining to your landlord, not the city. If you're not sure, call up Longmont Power & Communications and ask them what's up.

There are a few apartment complexes around Longmont that have resisted integration with the city's fiber network. My understanding is that the city has negotiated with each of them over the installation of fiber on their premises and that some of those negotiations didn't succeed, e.g. the apartment complex owners wanted to own and control the fiber that the city would pay to install.
