The last time all the root servers were down was June 28 1985.  On June 29
1985 there was a flurry of messages about adding root server down code to
the various DNS implementations of the day.  Apparently, some of the
software had a poor response to all root servers being unreachable, and
spun out of control.

Has anyone tested modern DNS code (Microsoft and BIND to name two) for
this condition recently?  I haven't, hence my question.

I'm certain that a lot of Linux users on dialups have their computers
boot up with an `all root servers unreachable' condition present, and
that the caching named's on their computers don't spin out of control.

To name but one scenario.
