I'm launching a new site soon and I expect it to make it into mainstream media. At this point, I'm not sure our server will be able to handle all of the requests.
Is there a way that I can detect the server running too slow so that I can just serve a static HTML page (similar to how Twitter does this)? Are there tools out there?
Unfortunately I haven't dealt with this before, a Google search doesn't give me any answers other than: make sure you loadtest your site. We did, and it's not bad, but I want a fallback. Installing it on a huge server isn't an option.
I'm using Win2008 and IIS7 on the server.
