To me, that part of it also points towards a broken implementation at
CloudFlare, letting a bogus (insecure) responses take effect anyway.
Or they prefer allowing people to visit websites over punishing
system administrators for operational failures that less secure (read:
nonvalidating) ISPs wouldn't inflict on their customers.
It's been quite common for DNSSEC-enabled recursors to add overrides
for outaged domains in situations like this.
It looks like the error has been mitigated, by the way, so this manual
override may not even have happened.
