Government Web Site is not Resolved

#1
Hi,

  1.1.1.1 seems to work great for 99.9999% of sites:

este:~> host www.google.com
www.google.com has address 172.217.5.68
www.google.com has IPv6 address 2607:f8b0:4007:802::2004

However, it does not work for this government web sites someone at my company needs access to:

este:~> host predict.cdc.gov
Host predict.cdc.gov not found: 2(SERVFAIL)

Yet, on this machine which is using  different resolvers

PLEIADES> host predict.cdc.gov
predict.cdc.gov is an alias for predict.glb.cdc.gov.
predict.glb.cdc.gov has address 198.246.102.73


Any clue? Thanks!
