High network latency in Vietnam (ISP Viettel) on November 22, 2022

Diag 1: https://nextdns.io/diag/5f4fa120-6a77-11ed-9a57-87e24dde685b

Diag 2: https://nextdns.io/diag/e0201a90-6a7d-11ed-9a57-87e24dde685b

The ultralow server is still working fine, but the anycast server is having high latency (2 servers are going to Europe). This is happening for almost 1 week now, I have checked Misaka there is no maintenance at this time.

Please check it out! Thank you!

    We've tried to reroute it to Hong Kong / Singapore however it doesn't work very well.

    Could you run a diagnostics again to see if there's any improvement?

      NextDNS Network Looks like it hasn't improved yet

      BigDargon Hmm, it looks like Viettel has different routing profiles and we're not able to affect the one that you're using. You can try using ultra-low latency servers instead.

      I tried this looking glass and it does go to zepto-hkg-1:

      NextDNS Network Thanks for the feedback and try routing! I still use encrypted DNS with the ultralow servers so I'm not affected by anycast servers.

    Anycast 1 server has been repaired, routing to hongkong (ISP Viettel). Thank you!
