I discover that servfail are not cached. is it normal?
explanation:
I have a cache-recursing server and i try www.blabla.com (which exist) and
then i stop the dns server of www.blabla.com. Then (after ttl expired) from
my cache-recusing server i try dig @0 www.blabla.com and i receive a
servfail, all this is OK. But this result is not cached means each time i do
my dig my server will try to contact the dns server of blabla.com.
Thanks;
Issam Harrathi.
