TTL Question

What dictates how long another name server caches the authoritative name 
server for a domain? I was under the impression it was the default 
time-to-live, but I have a situation where an authoritative name server 
was removed from service several days ago, yet queries to it continue. Dig 
is correctly reporting the new authoritative name servers for the domain 
in question. How common is it for DNS servers to ignore the ttl?
