---------------------------------------------------------------------- end of report
I bet somebody on the primary DNS made some changes to the zone data, but forgot to update the SOA s/n, so the ATT slaves didn't received the signal to transfer the updated zone.
Try incrementing the SOA s/n, and see if the slaves sync up.
