Question

How would you go about placing the site off-line if the database is down or the database adapter is missing / failed to load / etc.?

I am asking in the context of ASP.NET MVC 3 but this can apply for any ASP.NET site.

Let’s say somewhere around App_Start you load an assembly for data access and this is missing and/or something else fails. In this case the site can’t actually function.

I’m looking for a decent/elegant way to place the site in “Maintenance mode” just like App_Offline.htm works.

catch (ReallyBadException ex) {
    Utilities.EmailAdministrator();
    File.Copy(@"c:\templates\App_Offline.htm", @"c:\path\to\website\App_Offline.htm");
}
