This was just a mistake by WordPress and the blog is now restored. I remained fairly calm and within four hours activated my back up blog right here at xeno-lovegood.blogspot.com.
Unfortunately, I lost a night’s sleep scrambling to save my posts.
Blog disaster drill results: The blog xenophilius.wordpress.com currently has 9,437 Posts and 6,997 Comments in 42 categories. Only 1,141 posts could be imported to blogger.com from wordpress in 4 hours. Thousands of posts and comments could not be rescued due to conversion and file size errors.
1) Exporting the entire blog results in a file far larger than than 15 MB limit that can be imported by WordPress into a new blog.
2) Imports from WordPress to Blogspot are really lacking. Only 1 MB at a time can be imported, using a site that converts the exported WordPress .xml files to the Blogspot format, and there are many errors that happen during the process.
3) You people are awesome. Thanks for the email of support and extra points to those who found my back up blog right away by going to www.Xenophilia.com and following the link there to my new blog.
