Blue Coat Proxy
Would it be a bummer if you want your future employer to check out your website and the company's network blocks it? One reason is probably your website does not belong to any category. Being on the safe side, companies would treat your website just like the blacklist categories (ex. adult/mature content, social networking, gambling, etc).
To fix this, you can simply fill out your website information and category on the bluecoat site. Of course, let's be good citizens and fill out the form as honestly as possible.
