There was a issues with the delegation of some zones. NS records were not added to the parent zone when they should have been but the scripts which sign the zones added DS records which caused the parent zone not to be resigned. The signatures for the parent zone eventually expired which caused resolution failures for all the children of the parent zone rather than just the zones with a broken delegation.
The scripts that sign the zones did report the error but those reports were overlooked. Operations is looking at their proceedures and what additional checking can be done to prevent a repeat.
