Vietnam (Asia) is routed to anycast Spain (Europe)

Recently, I use CLI on Ubuntu and find that CLI is not connecting to utralow server anymore. When I tested anycast server it was routed to Spain, the speed of resolution and connection was extremely slow.

In Southeast Asia (with Vietnam), the nearest and fastest anycast servers are Hong Kong and Singapore. Hopefully this problem will be fixed soon, the slow speed will affect the user experience in the region. Thank you!

With IPv6, I check the network has IPv6, the server utralow does not have?

    You are connected using UDP (IP linking). If you installed CLI, you are not using it.

      Olivier Poitrey It seems you are misunderstanding, 2 completely different problems.  
       

      Issue 1, I am talking about a DoH connection and anycast is routing to a very far server.  Exactly here is Spain (Europe), while I'm in Vietnam (Asia)

       

      Second, utralow's IPv6 server has no search results.

       

      Please see the 2 analysis links I have posted above.  Thank you!

      BigDargon if you use DoH you will be on ultralow, so on a closer pop. This pop has no v6 yet but it doesn’t really matter, it will still resolve v6 addresses.
