Hi Colton,

We just had a long discussion in this forum to the effect that if a
city builds a greenfield access network, it would be best limited to
"layer 1" services. That is, deliver dark fiber and invite as many
service providers as possible to light it with whatever services
they're inclined to sell. Commercially, the L1 infrastructure presents
the barrier to entry. That's why you don't have enough competitive
commercial entities mooting the need to even discuss providing
Internet as a municipal service. Even the smallest city is attractive
to competitive commercial service providers when they can lease
in-place L1 infrastructure ad hoc.

This isn't as sexy as delivering gigabit Internet in the way roads
aren't as sexy as the cars which drive on them but it relieves the
city of having to make most of the hard-to-get-right decisions that
could tank your effort and turn it into a boondoggle. Let commercial
entities worry about what car will be popular next year and let
commercial entities figure out which stores folks will drive those
cars to. Just worry about where to build roads.

This. So much this.
