Your using the wrong tools to troubleshoot or investigate this error.

Instead of relying upon resolvers to provide situational awareness you need to inspect DNSSEC itself using dnsviz.net:


psc.gov is giving the world ID 5089 when they need to handing out ID 180.

Recommend the pms.psc.gov admins give the psc.gov admins the correct hash.

Subject: unresolvable pms.psc.gov, but google/cloudflare/unbound work

pms.psc.gov appears to be unresolvable against bind9.16.19
and 9.11.34 because of dnssec issues.
But it resolves against Cloudflare's, Google's, and an Unbound
resolver that does dnssec-validation.

There's a ticket open with nih.gov to look into it, but is there anything that can
be changed with Bind to make this domain resolve in the meantime?
