I am able to get notifications from certain feeds (http://fastpshb.appspot.com/feed/1/fastpshb and http://feeds.feedburner.com/foxnews/latest) but not http://rss.cnn.com/rss/cnn_topstories.rss. Is there a way to debug?
Also, just to be sure I'm going about it correctly, I am using https://pubsubhubbub.appspot.com/ for all communication (publishing my updates and subscribing), rather than separate endpoints of https://pubsubhubbub.appspot.com/publish and https://pubsubhubbub.appspot.com/subscribe. Is that correct?
