What is the name of the domain?

www.nrc.gov

What is the issue you’re encountering

nslookup on www.nrc.gov fails with SERVFAIL

What steps have you taken to resolve the issue?

Tested nslookup on multiple distinct networks, and all fail DNS lookup on this gov domain (Nuclear Regulatory Commission) on Cloudflare DNS. Other tested DNS (like Google 8 8 8 8) return an answer.

What feature, service or problem is this related to?

DNS records

Not sure why the other resolvers don’t report it, but looks like a DNSSEC RRSIG expiry issue with the nrc.gov domain.
