I make an app that connects to Facebook and Twitter and from time to time I get emails from people about this functionality being broken. I've taken steps to mitigate the problem however I would also like to add a feature which tells the user if the networks are down so they know it's just a temporary issue. Facebook has a JSON page that I can read to find out the current status in my app.
http://www.facebook.com/feeds/api_status.php
However I cannot find a Twitter equivalent. Does such a thing exist?
As a side question is the Facebook one documented anywhere? I'd like to know what to expect it returning when things are not so good.
