[Pdns-users] multi dns server

[Victor Hugo dos Santos]

Hello there,

The quantity of the domain, not necessarily reflect the quantity of
queries/load.
you can have 5.000 domains with 1.000 QPS or you can have 1 domain
with  15.000 QPS !! :-)

Anyway, you should monitor your servers and see if this issue is some
kind of "normal" stuff or some kind of problem (attack, data leak,
misconfiguration, etc). When you detect the problem, then you can
decide what to do.

About NS3, NS4, it is a totally valid option, not only to balance the
queries between servers, but to improve your HA too !!! Nevertheless,
you still need to detect where the problem is, if not, you are only
going to spend time with the new NS server but the problem will still
occur.

Let us know what you find.

Good luck
