What is Maintenance Mode?
Maintenance Mode is a term you use when you need to take your regular site offline to perform software of content updates. So for example, when WordPress needs to update itself, a plugin or a theme it has a built-in maintenance mode it uses to display a message to visitors that your site is down. Or say you have redesigned your site and you need a few hours to implement the new design. In this case you would use a maintenance mode plugin to put you site into maintenance mode so you can access the site to make your updates but your visitors would get a custom message about why it’s down and when it will be back up.
So essentially WordPress has two versions of a Maintenance Mode.
- WordPress Built-In – to do core, plugins and themes updates. Note, when WordPress puts itself into Maintenance Mode to perform updates you can not access any part of the site. The front end or the admin back-end. WordPress returns a default message that says: “Briefly unavailable for scheduled maintenance. Check back in a minute.” This message can be customized.
- WordPress Maintenance Mode Plugin – to perform updates to your site, but visitors see a custom message.

You should use this type of plugin when you need to perform updates to your site and you don’t want your visitors to see the site in an incomplete or transitional state. These plugins should return something called a http 503 status which tell Google and other search engines that the site is down for maintenance and to come back later for indexing. You should not keep your web site in Maintenance Mode for an extended period of time or it could hurt your SEO.
