How CloudFlare works ?
Once your website is a part of the CloudFlare community, its web traffic is routed through our intelligent global network. We automatically optimize the delivery of your web pages so your visitors get the fastest page load times and best performance. We also block threats and limit abusive bots and crawlers from wasting your bandwidth and server resources. The result: CloudFlare-powered websites see a significant improvement in performance and a decrease in spam and other attacks.
CloudFlare’s system gets faster and smarter as our community of users grows larger. We have designed the system to scale with our goal in mind: helping power and protect the entire Internet.
