NextDNS outages - it is a daily routine now

NextDNS has been reliable, fast and really really great for me and my family - until January this year.

Something is not alright with the infra at NextDNS - daily outages both on UDP port 53 is now a common theme.

 

It first started with outages with DoT, and I reported the issue several times. Now the issue is affecting DoT, DoH and "normal" DNS over UDP.
This week, has been real bad. Forcing me to stop using it so I actually can work.

 

Please fix this, or atleast COMMUNICATE with your customers that is paying for the service. Provide us with tools that we can run periodically and submit reports with it.

My ISP is Telia, and I can confirm that other DNS-servers works - so it is not my connection that is borked.

I can't recommend nextdns to people or companies anymore, those who I recommended to use it last year have now switched back to google and cloudflare.

Here is the logs, the posting functionality does not even work...

    I am pretty convinced that the issue started when the web3 support was added into nextdns. Maybe some resolvers are overloaded....

     

    However, I have now canceled my plan, after almost two years. Feels really sad but I feel that I have not choice.

    Please share your IP in DM so we can investigate.

      NextDNS I have shared it a couple of times, but not really gotten any communication back.

      NextDNS 
      Do you have any more tools to report and diagnose outages?

      Since the one that you already provide does not work that good.
      As I said before, I want to provide more information - but NextDNS seems unwilling to collaborate in order to find the issue.

    For the first time (ever) I had an outage yesterday, and then again just now. I've shared my IP address via DM.

    So I had to disable "private DNS" on some android devices this morning, since they had this issue aswell.

    Any news regarding this?
    Is the NewDNS staff not able to answer here on this forum? Or is this forum only for users communicating with other users?

    I'm having the same problem. Sent the staff a DM with no response. Sent them another this morning as the problem is back again.

    The problem is back (started 20 min ago).

     

    No response or reply from NextDNS on any of my DM's for the last few months. 

     

    This is very very bad customer service, and I'm a paying customer...

    Hi, I have the same problem since January.  I have daily outage that last for a couple minutes, especially in the evenings (Past 4 p.m., CEST UTC/GMT +2 hours).

    When it happens, the connection to the DNS-Server will first get slower and the latency will go up.  Than there will be the outage and when the connection is restored, the latency will stay on a high level until the next day.:

    https://nextdns.io/diag/40d1dd90-c323-11ec-8481-676889dfe9b3

    Normally the latency should be down to around 10ms.


    Thanks for your help in advance!

    And here we go again. NO REPOSE FROM NEXTDNS DNS SERVERS (and also the NextDNS staff, go figure). 

     

    DNS has been down since 06h10 this morning. It's now 08h10. 

     

    Running on Quad9 once again until NextDNS or the staff wakes up

      DynamicNotSlow if only it had the same functionality at NextDNS, or another provider. If you do find an alternative, please let me know?

      Jaco Marais I can only recommend Quad9 but you can a look at new Adguard DNS (beta).
