As of 1:35PM Victorian time the domain was renewed.  Some of the nodes for the 
8.8.8.8 service are still not resolving it while some already have the updated 
data.  Probably that will be the case for a lot of big DNS servers, but I 
expect that it will all be working in 20 minutes or so.

So you can delete such custom configuration in your DNS setup.

It would still be good to solve this technical problem.  This should be easy 
to do!  I really should write more blog posts of the "here's 2 lines of shell 
script that took me a week to work out" genre because I have solved this in 
the past.
