Many thanks !  I was only  talking about in the case if the backbone, where
is the dnscache, has a routage issue.
(i know that there is already a monitoring on root server 24/24 7/7).

I didn't know it s possible to disable recursion and serve the requests from
the cache only.

Could you say me the way to do this kind of dns configuration ?

Thanks in advance,
