Selecting Optimal Location

I've noticed that new name server locations have launched near me. When running https://ping.nextdns.io, I see they are half the latency of the previous closest location. It looks as though NextDNS CLI/anycast is still defaulting to the old location.

Is there a reason this is happening? Is there any way to force the use of the closer location? 

My diagnostic logs can be found here.

    The ping.nextdns.io output is confusing as it shows you anycast primary/secondary PoPs. Although, those new locations are unicast only locations. As per your diag output, CLI is currently using:

      Olivier Poitrey Thank you for clarification. Why is the diagnostic tool also running the trace route on the locations in Dallas? Is it running against the primary/secondary anycast servers, not the active lookup server?

      Mike L. because the diag tool goal is to diagnose anycast routing issues. Unicast steering is rarely if ever wrong.
