WordPress Publishing Old Feeds

Hey guys, this is a weird one — I recently switched servers, and have published 8 new articles since the server swtich. My RSS Feed will randomly post the new articles for several minutes, then i’ll check back later and they’ll be gone. They go on and off like this.

Now, i also updated the image source for the new feeds so images will display in feedburner, but the updates don’t show up when it only posts the old feed. Is it possible for wordpress to publish an old feed? Is there a cache issue that I’m missing?
