Are both instances using the same ISP and DNS upstream resolver
(from the ISP)?

Hello,
we notices the name "www.revenue.ie" is un-resolvable via one of
our unbound instances.
while looking for reasons we found no problem on a standby system.
unbound-1.8.1 configuration is *identical* (except listen ip)
The issue is reproducible even after restarting both instances.
neither http://dnsviz.net/d/revenue.ie/dnssec/ nor
https://zonemaster.net/result/de1eaf5bb0b9a596
show (me) an obvious reason.
Some random tries later I configured "domain-insecure: revenue.ie"
which solved the problem.
Cold someone explain that behaviour? Maybe we could learn again
some more experiences debugging strategies ...
Thanks
Andreas
