odd dig results for fqdn

[M. Meadows]

Thank you Tony. 
 
I see a cname pointing to another cname in this output. Is that the invalid cname? 
I thought that sort of record was discouraged but not against the rules. 
When I do a query on these cnames I get answers that seem meaningful.
I wonder why this would cause the odd results we are seeing ... where dig on fqdn fails until we do dig with +nssearch on the domain?
