From a business perspective, CEO of Corp X indeed doesn't give a rat's
backside on why it won't work.
But technically it'd be more interesting to note which RHS CNAMEs
are failing to resolve over TCP. What you then do with the data...
Diligently contact the respective RNAMEs in the respective zones
and tell them their DNS is borked (gee, will the RNAME work when
TCP is disabled ?). Or publish the original requested names AND
the CNAME culprits on a blog, and title it "These companies will
soon stop doing business together".
