Ultralow servers in Vietnam are unstable 10/05/2023
Hi,
Since the greencloud-han server moved the datacenter from Viettel to FPT, the server is routing to HongKong. DNS queries are redirected to the anexia-han server, making ultralow servers unstable.
Diag: https://nextdns.io/diag/2058ebf0-ef3f-11ed-a343-4fe8f47cf0de
I did the test using Mikrotik's traceroute tool, the results averaged over 146ms (dns1.nextdns.io). Meanwhile, routing to dns2.nextdns.io has to go through nodes (from 9 to 12) in HongKong.
Currently, the query to the ultralow servers in Vietnam is currently unstable. Unstable frequency occurs more often in the evening.
Please check and fix it.
Thank you!

The servers are unstable, resulting in a (first time) new domain query with no DNS records returned.
But then reloading the page is still working but also not stable.

Update: Maybe dns1.nextdns.io fixed it, ping is no longer more than 3xx ms.
dns2.nextdns.io accessed from Viettel ISP still routing to HongKong

Update: Both servers in Vietnam are working and routing stable. Hopefully NextDNS will have more servers in Ho Chi Minh City in the future!
