No longer updating

Everything worked fine yesterday, but my feed is not updating today. The RSS is working fine (see it at http://pipes.yahoo.com/pipes/pipe.inf... ), but Twitterfeed isn't pulling it or posting to the @VizWorld account.

I would think it was related to the Apple Keynote, but an 8am (Eastern) update didn't make it through either, and that was 4 hours before the keynote..
