http://www.prebleny.com/: Increase in server errors
Google detected a significant increase in the number of URLs we could not access. It is likely that your server had an internal error or was busy when attempting to process these requests.
The reason is that those URLs no longer exist. They were lost when I moved the blog here. I'm going to look into getting all the 404 error pages switched to here. I have the entire database of all those pages for anyone who wants it. Just email me at email@example.com
