Very impressive CloudFlare.

Where are you testing from? I'm going to guess: a datacenter. Residential customers won't see anything this fast. I'm in a small town in Kansas, connected by 1 Gbit ATT fiber. I'm getting ~26ms to 1.1.1.1 and ~19ms to my private DNS resolver that I host in a datacenter in Dallas. Google DNS comes in around 19ms.

I suspect that Cloudflare and Google DNS both have POPs in Dallas, which accounts for the similar numbers to my private resolver. My point is, low latencies to datacenter-located resolver clients is great but the advantage is reduced when consumer internet users have to go across their ISP's long private fiber hauls to get to a POP. Once you're at the exchange point, it doesn't really matter which provider you choose. Go with the one with the least censorship, best security, and most privacy. For me, that's the one I run myself.

Side note: I wish AT&T was better about peering outside of their major transit POPs and better about building smaller POPs in regional hubs. For me, that would be Kansas City. Tons of big ISPs and content providers peer in KC but AT&T skips them all and appears to backhaul all Kansas traffic to DFW before doing any peering.

If you are on ethernet, I am able to get 1-2ms pings. On same AT&T Fiber Gigabit. Wifi ruins both bandwidth and latency for me.

AT&T Fiber Gigabit in Nashville TN.

Pinging 8.8.8.8 averages 8ms. CloudFlare must have a POP here in Nashville?

That's probably because AT&T is using 1.1.1.1 for something internal and breaking the public internet for it's users: you get a really fast ping on 1.1.1.1, but it's not the 1.1.1.1 you are trying to reach.

Is this just speculation or can anybody confirm?

    traceroute to 1.1.1.1 (1.1.1.1), 64 hops max, 52 byte packets

Seems AT&T uses 1.1.1.1 inside of their modems. Oops!

Using 1.0.0.1 works.
