      Geen reacties op Shift8 CDN


This is a plugin that integrates a 100% free CDN service operated by Shift8, for your WordPress site. What this means is that you can simply install this plugin, activate and register with our CDN service and all of your static assets on your website will be served through our global content delivery network.

Newly added entpoints

New endpoints added :

  • Warsaw, Poland
  • Singapore
  • Dallas, TX, USA
  • Miami, FL, USA

Free Content Delivery Network for your Static Content

Shift8 has rolled out a consistently-growing CDN with endpoints all over the world. This plugin will make your site load way faster by using latency-based and geographic-based DNS resolution for requests made to your site to be served by an endpoint closest to the user making the request. This means that a user making a request in Mumbai, India will hit the Mumbai server to download the static content from your website, improving performance remarkably.

Current endpoints in use (more added regularly) :

  1. USA – Northern California
  2. USA – Northern Virginia
  3. USA – Dallas, TX
  4. USA – Miami, FL
  5. Canada – Toronto
  6. Europe – London, England
  7. Europe – Stockholm, Sweden
  8. Europe – Warsaw, Poland
  9. Asia Pacific – Hong Kong, China
  10. Asia Pacific – Tokyo, Japan
  11. Asia Pacific – Sydney, Australia
  12. Asia Pacific – Singapore
  13. Asia Pacific – Mumbai, India
  14. Latin America – Sao Paulo, Brazil

You can learn more about how the CDN was setup and how it works by reading our blog post.

I tested it on my site and its not working for me!

Send us an email to or post in the support forums here and we will help. We are constnatly improving and updating the plugin also!

I noticed on lazy load images, the CDN isnt being used

This is a known issue with how lazy loading is implemented in some scenarios. Currently if you want the CDN to be used for lazy load images, you have to turn lazy load off.


This section describes how to install the plugin and get it working.


  1. Upload the plugin files to the /wp-content/plugins/shif8-cdn directory, or install the plugin through the WordPress plugins screen directly.
  2. Activate the plugin through the ‘Plugins’ screen in WordPress
  3. Navigate to the plugin settings page and define your settings
  4. Hit the “Register” button to register your site with our CDN network.
  5. Within a few minutes the change will propagate to all our systems across the network.
