What is a CDN?

CDN = Content Delivery Network

How it works:

CDNs serve content stored at servers closest to the visitor.

The result -> pages load faster

  • CDN technology has been around a long time. The web’s largest sites use CDNs for performance.
  • Until now, CDNs have been expensive and hard to configure.

Easy Web Content Optimization

CloudFlare makes web content load efficiently by:

  • Consolidating multiple network requests into one request
  • Loading JavaScript asynchronously

The result -> pages load snappier


Web Content Optimization

The webpage has evolved.

Today websites are made up of:

  • Widgets
  • Plugins
  • Ad servers
  • Twitter Share / Facebook Like button
  • All of these plug-ins and widgets are JavaScriptbased
  • Web content optimization makes sure the web page renders as quickly as possible

CloudFlare’s Default Security is “Medium"


  • Users can select the desired level of protection directly from their control panel
  • Partners integrated via cPanel also have access to the “I’m Under Attack” mode

Stop Heavy Attacks From the Control Panel


  • Sites under attack can choose "I’m Under Attack Mode” directly from their control panel
  • Works by adding an additional set of protections to stop malicious HTTP traffic from being passed to the origin server
  • Reduces bandwidth to the origin server

Free IPv4 / IPv6 Gateway


Our customers can continue to host on IPv4 and be available on IPv6!


Why is IPv6 Compatibility Important?

  • IPv4 addresses are running out around the world. As a result, there is a transition to IPv6 IP addresses
  • IPv4 and IPv6 are not compatible with one another
  • Today, 1% of web surfers are on IPv6 and can’t reach websites on IPv4. Their number is growing fast in Asia & Europe.
  • To make website servers IPv6-compatible requires an expensive hardware investment

Always Online (Forget 503 Errors)

CloudFlare Always Online service keeps a cached copy of your customer’s website so it is always available, even if the server goes offline
