    Description

      Plenty of good articles for why this is better eg:

      http://stackoverflow.com/questions/2786595/what-is-the-correct-http-status-code-to-send-when-a-site-is-down-for-maintenance

      This is especially important for big sites with lots of publicly available and indexed pages so that google never crawls these and gets the outage page and indexes it.
