Undoing Blog Deletion
Once you Delete a blog, WordPress will send a notification email to your email address with information if the blog deletion can be undone within the first 30 days after the site is closed.
If you realize you've closed your blog by mistake, WordPress recommends that you reply to the notification email immediately, as after 30 days, all your blog data is purged and cannot be recovered. Your blog address will be deleted and cannot be used again.
