That's not what I was talking about. The issue is simply to be able to
reach a climair.be name server. With only two servers, probably in the
same room, they lose most of the reliability that the DNS can offer.

Same issue. Just two name servers (which is very low), probably both
in the same room (at least, they are behind the same BGP
announcement).

Define "positive". If your question is "if my dns device does not get
an answer from first NS RR, does he have to try on the other ones?",
the answer is YES.
