I'm sorry that the issue with Googlebot is occurring. We do not block the bot. The only way that it is blocked is typically through the robots.txt, .htaccess file, or possible issue DNS or the server being down itself. In this case your server is operational, and the DNS is okay. You do have quite a few entries in your .htaccess file that may be affecting it. You can actually find out what's causing the Googlebot issues by logging into your Google Webmaster Tools
account and then checking your website there. We have a series of articles on using the Google Webmaster Tools
starting with an introduction on its use. Google will be able to provide particular information on your site that should give you the details you need to determine why it's happening.
If you have any further questions, please leave a comment with more details and and we will be happy to review the issue for you.
