Hi,
For SERVFAIL to happen, ALL authoritative for the affected domains must
have been in Datacenters in Spain, Portugal or southern France.
I live in Spain, and as 12:33 CET I lost not only power but basic
telephony, cellular telephony and cellular data. Everything. Power
generators were only good for keeping power locally at Datacenters or
Hospitals, but they were isolated from each other.
The mitigation began at around 2-3pm CET , as they were turning up
different power plants one at a time and connecting it to the power
network, and it took them more than 12 hours to turn everything up.
So may be that was the reason, if it coincides with your perception ...
dnstracer has eventually helped me find lame delegations.

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?
