Anybody heard of CloudFare? Hostgator now uses them
We are proud to announce a new partnership with Cloudflare, Inc. to offer their Cloudflare protection to our customers. Cloudflare acts a transparent filtering proxy, sitting between your site and it's visitors. Cloudflare blocks hackers and spammers from attacking your site, and also speeds up load times by acting as a content delivery network and serving cached copies of your static files from a proxy which is closer to your customers. On average, Cloudflare customers have seen a 30% improvement in page load times. In it's basic mode, Cloudflare is free. We are the first host to integrate Cloudflare protection into our control panel. If you are a shared customer, you can enable Cloudflare protection for your domains by clicking on the orange Cloudflare icon in your control panel. We are working on a non-branded version for reseller, vps, and dedicated customers as well, but in the mean time our admins have a script to enable protection for any domain you would like. Simply open a ticket and let us know!
