When I used to work for an ISP, I ran a script every day that checked 
that all the zones we hosted were delegated to our servers.  When it 
reported a failure, I notified the customer we were hosting the domain 
for, and worked with them to resolve the issue (either fixing the 
delegation if it was changed in error, or removing the zone from our 
servers).
