However they will certainly start complaining when DNS stops working. Of
course they won't know that's what the issue is, but they will call
saying the internet is down.

Okay, then the first way I mentioned for checking should be
sufficient.  Well, perhaps make it

  dig 
$RANDOM.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.
 +dnssec

instead, so that you'll receive an even larger response.

But actually, you already know that your DNS can cope with responses
512 bytes, if you look at this:

  dig @k.root-servers.net  +trace +all +dnssec aol.com MX

Certainly, your users would complain if they couldn't send mail to
AOL. 8-)
