one more comment, the above situation when *all* servers for a domain 
are unreachable becoming normal today, it was not so frequent two,three 
years back, but today's viruses, and other vicious software can easily 
bring some poorly set up domain down.

And other recursive bind servers with their customers inflected by the 
same viruses will possibly have severe performance problems without even 
a single line in the log, effectively telling the administrator, "I have 
some so minor problem it doesn't even worth logging it, I can handle 
it..." can it really handle it?
