The TTL is controlled by whoever is in charge of the zone (your customer in 
this case).

Unless something truly was wrong (which seems to be common with MS DNS, but 
not bind), your DNS server was just waiting for the TTL to reach 0.  So it 
was behaving exactly as your customer designed it to.

Unfortunately, since you've restarted bind, there is no way to go back and 
see if there really was a problem.  If bind was still running, you could 
just check the TTL that it was reporting to see if there was a problem.
