The last time all the root servers were down was June 28 1985.  On June 29

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.


Microsoft DNS has a poor response and can spin out of control with all root
servers available.. how would you tell the difference ;)
