Yep, they're still expanding! It was all brand new fiber installations across several neighborhoods here. Dug up the streets everywhere for a few months. Mesa just opened up access to anyone that wants to install fiber. I know of different 3 vendors in the area who installed their own new lines.
I was surprised they jumped to our neighborhood so soon. I don't live near downtown Mesa where they started. But I am near a lot of new datacenters.
Yes, it's a triumph of capitalism that we have to waste the energy and materials to build out the infrastructure N times before competition kicks in to give us prices that were apparently possible (but not offered) all along!
It's a failure of democracy. Voters are not smart enough to understand the utility of ubiquitous fiber to the home as a utility, so they do not vote for leaders who prioritize that.
