Anyone seeing this from the cdc.gov nameservers?

    $ dig +cd +short ns akam.cdc.gov                            
    a1-43.akam.net.
    a2-64.akam.net.
    a5-66.akam.net.
    a8-67.akam.net.
    a9-64.akam.net.
    a28-65.akam.net.
 
    $ dig +cd +short ns cdc.gov                            
    ns1.cdc.gov.
    ns2.cdc.gov.
    ns3.cdc.gov.
    icdc-us-ns1.cdc.gov.
    icdc-us-ns2.cdc.gov.
    icdc-us-ns3.cdc.gov.
 
    $ dig +noall +ans +dnssec +nocrypt www.akam.cdc.gov @a1-43.akam.net                            
    www.akam.cdc.gov.       20      IN      A       23.197.246.11
    www.akam.cdc.gov.       20      IN      RRSIG   A 10 4 20 20201220195717 20201217185717 11552 akam.cdc.gov. [omitted]
 
    $ dig +noall +ans +dnssec +nocrypt www.akam.cdc.gov @ns1.cdc.gov                            
    www.akam.cdc.gov.       3600    IN      CNAME   www.cdc.gov.edgekey.net.

Because cdc.gov nameservers are responding to queries below their
delegations, and they’re responding without signatures, they’re being
considered BOGUS.

I’ll dig up a .gov contact in the OARC portal….
