So, just to keep anyone reading this on the same page, the question
seems to be something like "why does a host state not change from down
to unreachable when a parent node later goes down?"

I'm not sure I can anwer it, other than to give reasons why I think it
works the way it does.  When a host goes down, its parent nodes are
checked.  If they're OK, the host is marked down until it comes back up.
If not, it's marked unreachable until the parent node comes back up.

I would guess the behavior you're seeing is because Nagios is waiting
for the host to come up, and it's not taking *every* state change into
account.  This may be a bug, and it may be a feature, but it's
apparently the way it works based on your observations (which I haven't
attempted to verify).

If that's the case, and nobody here has been able to give you a helpful
response, maybe it's something to bring up on the nagios-devel list as a
bug or feature request.
