Longmont (which is ~12 miles north of Boulder) got municiple broadband a while back. https://www.longmontcolorado.gov/departments/departments-e-m... This also follows Fort Collins from 7 months ago: https://arstechnica.com/tech-policy/2017/11/voters-reject-ca... Note that Longmont took a couple attempts I believe to get it passed (it failed in 2009 and 2011, then passed in 2013)
Usually my speeds clocked in around the 700-900mbps range (both up/down), and at its slowest, maybe 300mbps. No port blocking, so I could host my own web/game servers. The one time they performed maintenance, they notified customers a week in advance and scheduled the 15-minute down time to be around 3am. Since I was a 'charter' customer, my bill was a flat $50/mo, though I'm pretty certain that new customers don't pay much more than that.
I truly believe if more people understood what _good_ internet is like, there would be a MUCH stronger push for communal broadband services.
