I'm curious if there is a module or a way to display a working copy of a Drupal website even when MySQL goes down. While obviously if MySQL goes down, it should be resolved, it would still be nice for the customer side and their audience to be able to use the website still.
Has anyone ever done something like this before? You wouldn't be able to login or make content changes of course. Is there a way using .htaccess or something that you could ping the site and if MySQL is down, redirect to a cloned site?
