Reply To: Possible RSS Feed Bug
You can test feeds with the W3C Feed Validator http://validator.w3.org/feed/
As to why your feed is failing I think is probably an issue with your web host as when I check your feed the results are “Server returned HTTP Error 404: Not Found” and I would expect IFTTT would also have problems parsing the feed.
