If, for example, your clients want to be able to “turn off” their website for a while, so they can work on new 
content or features of their website, but you don’t want them rummaging through the WordPress Settings pages to do so, this plugin might be something for you.
This plugin creates a very simple little widget for your WP Dashboard, from which the website can turned to / out of maintenance mode.
Activating maintenance mode will display a maintenance mode page with explanatory text for your visitors. Logged in users will be able to view the website as they normally would.
The plugin will automatically create a <code>maintenance.php</code> file and add it to your <code>/wp-content/</code> directory. Customize this page to change the appearance and text of the maintenance mode page.
Known bugs 
* Right now, this plugin will not work on certain servers (like Antagonist.nl) because of a permissions issue.

This super lightweight plugin is intended primarily for developers, designers and site administrators that need to allow clients to preview the site before being available to the public or to temporarily hide it while undergoing major updates.
Any logged-in user with WordPress administrator privileges will be allowed to view the site regardless of the settings in the plugin. The exact privilege can be set using a filter hook – see FAQs.
The behaviour of this can be enabled or disabled at any time without losing any of the settings configured in its settings pane. However, deactivating the plugin is recommended versus having it activated while disabled.
When redirect is enabled, it can send a different header types.
A list of IP addresses can be set up to completely bypass maintenance mode. This option is useful when needing to allow a client’s entire office to access the site while in maintenance mode without needing to maintain individual access keys.
Access keys work by creating a key on the user’s computer that will be checked against when maintenance mode is active. When a new key is created, a link to create the access key cookie will be emailed to the email address provided. Access can then be revoked either by disabling or deleting the key.
Whitelisted User Roles – user roles who see the site, instead of under maintenance page
