Are your load-balancers providing different DNS replies to different clients? Most organizations don't need to place the nameservers themselves behind a LB. > That works fine for test.example.com.

As I recall, I can’t just delegate , as an example, > www.example.com, then use a CNAME for example.com. You can't delegate individual records-- you delegate zones. If you had multiple DCs available, you might use a CNAME to point www.example.com to www.dc1.example.com, www.dc2.example.com, etc based upon whatever criteria seems reasonable, such as availability, client geolocation data, etc. For web traffic, it is common to set a session cookie or similar for session affinity to keep requests going to the same DC once a given client has landed there. You might want to have a chat with someone from Akamai, Level3, or one of the other CDN players.
