What I'd do is check to see if the following works (Note I have not
tested any of this)

  - use a deny_info override for that particular ERROR_PAGE
  - the new errorpage to refresh to the next slide-show page in sequence.

If that works, any pages broken during the downtime will simply be
skipped in favour of pages that do work.

You will most likely need a small http daemon/script to provide the new
deny_info page and keep track of what was meant to be next.
