Yes. You are right. We need enhance our urgent plan and monitoring for such event. 

I found in current plan only new IANA serial can trigger the update(the recovered zone). We are in passive position to react to such failures. If we issue out a new serial, it will be ahead of IANA serial and send no notify for next real serial when it's coming.
