Google has acquired Feedburner in 2007, and they have started migrating the feeds hosted on Feedburner to Google’s servers recently. Google also announced that they expect to get all the feeds transferred by February 28, and they mentioned that after that day Feedburner feeds will start reporting a 404. So most of us should have already migrated our feed to Google’s servers.

Because of the migiration, Google has released a new API for the feed stats which makes our Feed Analysis does not work properly. Therefore, we have decided using the new API for Feed Analysis, which makes migrated feeds work properly. However, if you have not migrate your feeds to Google’s servers, Feed Analysis will no longer work for you, please do the migration as soon as possible. Go and analysis your Google feeds now.
