DNS Resolution Issues

[EagleOwl3]

Dearest Group -

If I have multiple resolvers configured and then run a DNS Leaktest, I will see every configured resolver appear in the results. For some reason I was expecting just the top picked one to appear until the load balancer does its stuff again; this maybe a misunderstanding on my part.

The reason for this question is that I have had terrible DNS problems which manifests itself as websites not/partially loading. If I configure just one resolver, the problems disappear.

In my case, I am based in the UK and was selecting just UK resolvers. I wonder if it is a CDN thing?

Many thanks in advance.

A resolver can be fast for a query and super slow for another one. So, the selection is made incrementally, after every update.
Running a benchmark or a leaktest doesn't mean much. At best, this is hitting rate limits of resolvers due to the traffic spike, so the client falls back to less efficient servers afterwards.

The best way to see what servers you are using and how they perform is to enable the web UI.

Thank you - I have enabled the UI and will study that closely.
