BIND doesn't have anything built-in to support this. You can write a
script that runs via cron and periodically checks whether server-org is
running. If it's not, it edits your zone file to change the A record for
your web server to point to 126.96.36.199 and performs "ndc reload".
You could also investigate non-BIND solutions like 3DNS or Distributed
Director, which do this automatically.
