I am getting high latency in charlotte ,North Carolina with dns routed to Mexico. 

Noticed errors for: 

tier-clt (IPv6)          error

  teraswitch-pit (IPv6)    error

dns2.nextdns.io (IPv6) error (ultralow2)

I have a lot of clients reporting no connectivity at all.

Using my NextDNS CLI on my Intel NUC 12 Pro with Ubuntu 22.04.3 and pointing to my UDM-SE.
