Blogger has had issues and crashed sometime on May 11. Any posts put up from that date forward, have been saved by Blogger and and will be reposted by Blogger sometime in the next day or so. This is the message from Blogger regarding the outage:
We are very sorry that users are unable to publish to Blogger right now. We have rolled back the maintenance release from last night and as a result, posts and comments from all users made after 7:37 am PDT on May 11, 2011 have been removed. Again, we apologize that this happened and our engineers are working hard to return Blogger to normal and restore your posts and comments. We will post a report once this work is complete.
-The Blogger Team
