Hey,
This was reported on Mastodon[1][2]:
It looks like currently the NS for nih.gov only
respond to TCP queries.
$ dig +noall +auth +add @a.ns.gov ns nih.gov
nih.gov. 10800 IN NS ns.nih.gov.
nih.gov. 10800 IN NS ns2.nih.gov.
nih.gov. 10800 IN NS ns3.nih.gov.
ns.nih.gov. 3600 IN A 128.231.128.251
ns2.nih.gov. 3600 IN A 128.231.64.1
ns3.nih.gov. 3600 IN A 165.112.4.230
$ dig +short +noall @165.112.4.230 ns nih.gov
;; connection timed out; no servers could be reached
$ dig +short @128.231.64.1 ns nih.gov
;; connection timed out; no servers could be reached
$ dig +short @128.231.128.251 ns nih.gov
;; connection timed out; no servers could be reached
$ dig +short +tcp @165.112.4.230 ns nih.gov
ns.nih.gov.
ns3.nih.gov.
ns2.nih.gov.
$ dig +short +tcp @128.231.64.1 ns nih.gov
ns.nih.gov.
ns2.nih.gov.
ns3.nih.gov.
$ dig +short +tcp @128.231.128.251 ns nih.gov
ns3.nih.gov.
ns.nih.gov.
ns2.nih.gov.

Wonder if that's some DOGE fallout. I've reached out
to hostmaster at list.nih.gov (by resolving the IP
address via TCP and adding it to /etc/hosts :-), but I
wouldn't assume that this actually gets to somebody
able to fix things.
