  Bryan Shaw seems like you are using eerodns as your default DNS, which routes you to their Chicago PoP (136.144.60.227). This is why ultralow is misguided. You can try to setup a different (unencrypted) DNS in your router, it will fix your DoH routing.

  Nothing to do with NextDNS. You are probably using a VPN service. Some browsers have VPN integrated.

Getting routed through CPH even though I'm in Switzerland. Resulting in very high latency (can for some reason not upload a screenshot)

Could you please take a look at my diagnostics report?

I'm in Northern Virginia, but constantly connecting to slower servers in Atlanta.

Seems ultra low servers are slower. Why is that?

Hi just wanted to check to see if my setup looks ok. It's setup on my asus ax-11000 with merlin firmware on the nextdns CLI client. When I go to ping.nextdns.io website it doesn't always hit the lowest latency server.
