Feedburner RSS not recognizing WP Feed

Site: http://www.peanutbutterboy.com
Feed: http://feeds.feedburner.com/peanutbutterboy
WP 2.6.2

For 2 days now, Feedburner will not recognize any feed I enter for “original feed”. I have tried http://www.peanutbutterboy.com/feed, /feed/, /?feed=rss2, /?feed=atom, /index.php?feed=rss2, etc.. I always get a “Connection Reset” or “Read Timed Out” error. I’ve even uploaded my old atom.xml and rss.xml files to my main directory and Feedburner cannot recognize them either.

I have Permalinks set to /year/month/post-title and have checked the .htaccess file and all other settings I can think of. I have disabled all plugins and tried the default theme, all to no avail. Any of the feeds are accessible directly, Firefox/Google/Feedblitz/Feedvalidator all recognize the feed, but it seems like my site is blocking feedburner for some reason. I’ve also heard reports from a few people at different geographic locations that even my site is not accessible. Is WP blocking some incoming connections?
