Fixing Magento “Service Temporarily Unavailable” error

Sometimes Magento will display a “Service Temporarily Unavailable” message. The message will look like the following:

Service Temporarily Unavailable

The most common cause of this issue is a file located at [Magento root]/maintenance.flag. If this file exists, then Magento will display this message. The purpose of the file is to put the store into maintenance mode when doing maintenance. However, if someone forgets to delete it, then it will continue to display the message even after maintenance. To resolve, simply delete this file.
