... and for those of us who prefer the pretty graph version:
Another thing that is interesting is:
$ dig covid.cdc.gov @ns1.cdc.gov
;; ANSWER SECTION:
Covid.cdc.gov. 3600 IN CNAME covid.akam.cdc.gov.
covid.akam.cdc.gov. 3600 IN CNAME covid.cdc.gov.edgekey.net.
The uppercase 'C' in the 'Covid.cdc.gov. 3600 IN CNAME
covid.akam.cdc.gov.' from the auth is interesting... Not wrong, just
