Hi,
on a leased server it's suddenly today no longer possible to resolve the A
record of savannah.gnu.org while on my home PC there are no such problems
(besides of my default provider nameserver I tested also the Google
servers google-public-dns-a.google.com and
google-public-dns-b.google.com).
The provider of the leased server gives on my inquiry the following
answer (the translation to English may not perfect):
Since our nameservers validate DNSSEC and on the side of gnu.org are
errors in the DNSSEC configuration our nameservers cannot resolve that
domain: http://dnsviz.net/d/savannah.gnu.org/dnssec/
And indeed the mentioned page complains:
Errors: The NS-bit was nor set in the bitmap of the NSEC RR
corrresponding to the delegated name (savannah.gnu.org)
and
Description: Delegation from gnu.org to savannah.gnu.org, statis: BOGUS
By the way the A record of for e.g. www.gnu.org is on the
mentioned server resolvable.
Sorry, I am a complete DNSSEC layman and want only report that problem.
Jens
