Another thing you can do is to have a app_offline.htm in the root folder of your site.
A template can be found here: http://geekswithblogs.net/Vipin/archive/2012/03/28/app_offline.htm-taking-site-down-for-maintenance.aspx
The reason why I am copying this url is because some say there is a need for a minimum size for the file.
