To the outside world, there's no distinction between a "primary" name server and a "secondary" name server. Any name server listed as being authoritative for your domain is considered to be as authoritative as any other, and your secondaries are as likely to be queried as your primary. It's not like the situation with mail exchangers, where secondary exchangers are used only if a primary can't be reached. There's no concept of priority with name servers. The difference between a primary and a secondary is visible only to an administrator. The primary is where the records live, and a secondary loads its data from the primary. BIND 8.1 has changed the terminology to "master" and "slave" to better describe the relationship.
