For some reason, every time I shut down my 1st unbound DNS resolver, most of my clients stall and wait for replies until a timeout is reached. Then and only then will they switch to my 2nd unbound DNS resolver.
I was thinking of using CARP to have only one virtual IP for the clients to use, so if the 2nd unbound jail takes over, the clients won't even notice.
Does this make sense or is there a better way to deal with this? ๐ค
