Now that the API is all done on stackexchange.com. What happens if say just certain sites go offline (eg just Stackoverflow). Will the API continue to return results or will it return the HTML offline page?

Also if the whole network goes offline (as it did earlier today it seems), can we pleas have a JSON response rather than HTML?

Also the HTML response (when the network is offline) for the authentication route should be about the same size as the dialog is when online. I know all the Open ID providers have different size login pages, but they are on different domains so can be identified easily. Whereas if the network is offline and a user tries to authenticate, the domain (and I'm pretty sure the URL is the same as when it works) is the same.

At the very least can we have some documentation on what happens when the site/network go offline?
