> I have a server configured with 2 nameservers in {{resolv.conf}, and only the first one is responsive. I'm getting DNS timeouts on every new request while it fails over from the broken one to the good one.
> It is also really hard to debug this because none of the debug logs explicitly tell you what is going on with each server.
> First, this behaviour seems pretty suboptimal. Second, we need better observability (even improved debugging) that would help an operator figure this out.
