There was some data corruption that impacted Blogger’s behavior. Since then, bloggers and readers may have experienced a variety of anomalies including intermittent outages, disappearing posts, and arriving at unintended blogs or error pages.
Infact the post for May 12th Silverlight 4 DataGrid Filtering using DataGridColumnStyle was not available for a couple of hours. After 20 hours of unable to post, happy to be back again!
Back to blogging now...
