Very true.

The solution is to turn DNS resolves to appliances, with clear labels 
"DNS resolver". Then we can leave the task of restarting the appliance 
to whoever needs Internet there. Just as they will do with any other 
device which has power switch or cord.

Adding a label "no user serviceable parts inside, in case of malfunction 
call ... " will help further.

For those who do not pretend to be ignorant, setting up and 
"maintaining" recursive DNS resolver is trivial.

By the way, 10% is ok. ;-)
