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.
