If you missed to read Google webmaster central last blog post about Google Webmaster Tools Site Error reporting data.
So enjoy reading
Today we’re announcing more detailed Site Error information in Webmaster Tools. This information is useful when looking for the source of your Site Errors. For example, if your site suffers from server connectivity problems, your server may simply be misconfigured; then again, it could also be completely unavailable! Since each Site Error (DNS, server connectivity, and robots.txt fetch) is comprised of several unique issues, we’ve broken down each category into more specific errors to provide you with a better analysis of your site’s health.
Site Errors will display statistics for each of your site-wide crawl errors from the past 90 days. In addition, it will show the failure rates for any category-specific errors that have been affecting your site.
If you’re not sure what a particular error means, you can read a short description of it by hovering over its entry in the legend. You can find more detailed information by following the “More info” link in the tooltip.
We hope that these changes will make Site Errors even more informative and helpful in keeping your site in tip-top shape. If you have any questions or suggestions, please let us know through the Webmaster Tools Help Forum.
