... every once in a while users are getting "Site Off-Line" message when trying to access Drupal6 (Pressflow), so I start looking into following document to modifiy template and possibly provide me with a reasoning on why Drupal keeps doing that..
Theming the Drupal maintenance page | Drupal.org
What should be included into new template page? I was thinking at least this one:
PHP: mysqli::$connect_error - Manual
but what else would be useful in order to troubleshoot site offline??

Thanks, it was faulty dns
Thanks Dave. It turned out to be a problem with DNS not resolving 100% of the time. When it wasn't resolving the IP of the DB server we would get the site offline message. After we added the name/IP in the hosts files on both web heads it appeared that everything was perfect. Weird that we never encountered this during the tests. Thanks for your feedback though.
We ultimately found this out by altering the maintenance page in the core to see an error on the site offline page.
Maybe it's combined in with
Maybe it's combined in with the Apache logs?
