for those who are debugging weird failures in DNSSEC validation, please
note that NS for coop. TLD provide broken proofs of non-existence. This
sometimes lead to cascade failure e.g. for domain existrans.org. which
has NS pointing to ns1.ouvaton.coop.


If there is anyone from coop., feel free to get in touch with me.
