If he has a small number of slaves, the OP may not need a Tardis.  It's 
possible to just edit the cache files.  It's UGLY, you need to make sure 
you hit all the slaves, and they will get overwritten the instant your 
master returns from the dead ... but that latter's a good thing.

About this master being offline for some time due to a disk failure ... 
that policy may need review.  If the OP serves his organization's DNS, it's 
pretty darn critical that customers be able to resolv their DNS info.
