Ping FeedBurner
Ping FeedBurner using this form and we'll update your feed immediately, instead of on our automatic 30 minute interval. Provide the address of the Web site hosting the source feed (example: http://www.myblogsite.com).
Hint: Bookmark this page after hitting the "Ping FeedBurner" button and use that bookmark as a handy way to update your feed from your bookmarks menu! This form uses FeedBurner's underlying Ping and Extended Ping XML-RPC API.
Looking for PingShot, our super-helpful service that automatically notifies directories and aggregators when you publish new content in your feed?
