You could use an App_Offline.htm file. Simply upload an html file with this name to the route of your ASP.NET application and all requests will route to it. When you are ready to put your site back online simply delete the file. There's a small gotcha you should be aware of when using App_Offline.htm file with an ASP.NET MVC application.
