vultr-fra (IPv6): high latency

Hello,

 

I'm experiencing high latency ONLY on vultr-fra (IPv6) of about 100ms. 

Unfortunately the nextdns client seems to love to switch to that node despite the high ping. 

Also submitting a report via the diagnostic tool fails with 

Post unsuccessful: status 400
{"error":"0: instance.Test requires property \"Client\"\n"}

If you need any more traceroutes I can do these with mtr.

    The latency issue I reported above persists; vultr-fra (IPv6) is always around 100 ms while all the other -fra servers are usually <10 ms.
    Could I get some support, please?

    As the report shows, you are not using this server. Why is it a concern?

      NextDNS The Linux nextDNS client connects to all of the -fra servers, including the
      slow one, regularly. 
      I wrote this in my 1st post and I also added the data from ping.nextdns.io where you can
      see the black square next to the slow server, indicating that I was indeed connected to it.

      When this happens browsing the web is noticeably slower.
