^^^^^^^^^^^^^^^^^^^^^^^^^^^^ This is a problem right here. The name of the domain
cannot be a CNAME. CNAME's can't co-exist with other record types. You have 2
NS records and 1 SOA for "saddomain.com", so that name cannot also be a CNAME.
Instead, you should add an A record with whatever address
"www.sierra.com" resolves to.

It's difficult to tell whether this is the root cause of your problem, given that
you've "fictionalized" the domain names. But fix that and see what you get.
