Theming Site off-line page Is there any way to theme or override the Site off-line page?

The page with below massage:


  The site is currently not available due to technical problems. Please try again later. Thank you for your understanding.


This page uses Garland by default and it has Drupal logo on the page.
I would like to remove this Drupal logo and also change the texts.
Yes, there are 2 templates files that handle this in your theme:


maintenance-page.tpl.php: The theming template used for when your site is in maintenance mode.
maintenance-page--offline.tpl.php: The theming template used for when your site doesn't have database connectivity. 


Read Theming the Drupal maintenance page on d.o for more information.
