Colorado Springs routing through Chicago: update

*tl;dr T-Mobile improved some routes, but most latency is nerfed.*

*(*[*Follow up to my last post*](https://www.reddit.com/r/tfiber/comments/1v14x1z/colorado_traffic_is_routing_through_chicago_again/)*)*

Traffic from Colorado Springs has been routing out of state in a consistent way until October 12, when T-Fiber changed routing. There were a complex series of changes, so this is a simplification. One day was a big upgrade: traffic to Colorado Springs was 6-8 ms, Denver was 4-6 ms, except Google which was 14ms.

Then on October 14, most traffic was routing out of state again, but 12 hours later (Oct 14 10pm) 8.8.8.8 responded faster than Metronet's speed test server.

There was a brief improvement for \~12 hours October 19-20. Since then, most traffic is out of state except one host in Colorado Springs (Force Broadband) and 8.8.8.8. Other hosts in Colorado Springs and Denver are much slower.

Below is a snapshot of the current T-Fiber status.

Meanwhile, G-Fiber will be replacing Ting in Colorado Springs.

# Google: two latency tiers

DNS for these names returns different Google IP ranges, served from different sites over the same local path (mtr shows the same first hops as 8.8.8.8): \~4 ms for 8.8.8.8 and 142.251.x (www.google.com, googleapis.com), \~14 ms for 74.125.x (google.com), 172.253.x (fonts.googleapis.com), and 173.194.x (gstatic.com). The \~14 ms tier was already there during the Oct 12 in-state window, so it is probably Google's anycast rather than the Chicago routing.

# mtr (October 26)
