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.

    round-trip min/avg/max/stddev = 0.688/0.891/1.387/0.204 ms

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.

[nodesocket]

Is this just speculation or can anybody confirm?

    traceroute to 1.1.1.1 (1.1.1.1), 64 hops max, 52 byte packets
     1  1dot1dot1dot1.cloudflare-dns.com (1.1.1.1)  1.117 ms  0.710 ms  0.727 ms

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

Using 1.0.0.1 works.

Given that they're a CDN, I would expect them to. I'm jealous that BNA has AT&T peering but Kansas City has minimal/no peering.

haha, I knew that was you when I read Nashville, nodesocket

You should invest in some better wifi gear, it sounds like!

On a Unifi nano hd, with moderate signal, my latency only goes up 1ms.

Getting ~3.5 ms on wifi to 1.1.1.1, ~2.5ms ethernet

[hartator]

That's impressive. My AT&T wifi router caps bandwidth at 300mb/s (instead of 1gbs on ethernet) and add 10-20 ms to latency. And this is standing next to it and using 5ghz.

[snuxoll]

Man, wish I could ever get pings this low - the link from my VDSL2 model to the local CenturyLink CO alone is 8-15ms depending on the day.

Sucks that VDSL2 no longer supports fastpath, not that I could use it on an ADSL line due to bonding anyway :/

[fudgy73]

Out of curiosity, what is your complete Unifi / network setup?

[cthalupa]

GW/Firewall: USG-XG Switches: 2x US-16-XG, 1x US-48, 2x US-8 APs: 2x Nano HD, 2x AC Pro

[chrissnell]

I'm on Ethernet and fiber all the way. This may have to do more with how AT&T has constructed their fiber in this region. Where do you live?

How did you get that beautiful traceroute output?
