In that case, someone smarter and more knowledgeable on this list will
hopefully help you. But first - one last suggestion - if you find that
forwards to 3rd party servers work - but turning those off causes issues
- you should probably make sure that your "root hints" are updated, and
purge any caching (rndc flush), then restart BIND. Maybe you've already
done that? But if not, it's worth a try before digging deeper.
If that doesn't fix this, then hopefully someone else on this list can
help you.

Subject Re: Massive increase of SERVFAIL after April 28th 2025.
Hi Rob,
Unfortunately, as soon as I remove the 'forwarders' in any of my named servers,
the problem comes back. The output in my previous message was captured just a
few minutes ago after I had disabled 'forwaders' in one of my bind servers.
Regards,
Vincent

until a few days ago (April 28th?) when the amount of SERVFAIL started
going ballistic and started preventing the resolution of a lot of DNS names on
the internet to
the point where DNS was unusable
I strongly suspect that this was caused (even if indirectly?) by the MASSIVE
and many-hours-long power outages in Europe, mainly in Spain and Portugal. That
started on April 28,
2025, at approximately 6:33 a.m. Eastern Time (ET) - and the majority of it
lasted almot 24 hours.

Hopefully, you're not seeing any more of these errors now?
