I didn't get to play detective at the time of the outage, but 
configutation (which is automatically replicated) may also have been 
enough to take out both nameservers.

It also makes good management sense to run your nameservers with the 
same software and versions, but perhaps it doesn't make good continuity 
sense.. ?
