Hi,

I really like NextDNS's ultralow server feature, which helps us (NextDNS users in Vietnam) use a local server that no 3rd party DNS service has yet.

But there is a problem here, 2 servers are located in Hanoi (in the North) and many users in Ho Chi Minh (in the South) DNS queries go quite far.

I'm living in Ho Chi Minh and here are my diag results: https://nextdns.io/diag/f1d3f0c0-ece8-11ed-952c-b120037c8afe

As far as I know, F-Root server has anycast server in Ho Chi Minh. This is very convenient, if NextDNS adds/move servers to Ho Chi Minh.

 Here is the traceroute and dig commands from where I live

I'm recommending friends, colleagues, .. to switch to NextDNS. Among them, many have paid monthly/yearly fees to use. Hoping for the above (and the large number of users in Vietnam), NextDNS will consider adding/moving a server in Ho Chi Minh.

Thank you!
