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

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. Europe – Frankfurt, Germany
  10. Europe – Ukraine
  11. Asia Pacific – Hong Kong, China
  12. Asia Pacific – Tokyo, Japan
  13. Asia Pacific – Sydney, Australia
  14. Asia Pacific – Singapore
  15. Asia Pacific – Mumbai, India
  16. Latin America – Sao Paulo, Brazil

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

FAQ

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

Send us an email to cdnhelp@shift8web.com or post in the support forums here and we will help. We are constantly 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.

Just wanted to show my appreciation for this free CDN service. It works great on media files (which is what I wanted it for), the plugin is updated regularly and they keep adding new points of presence. Well done and thank you.

This team is awesome I used only the media file setting and my website with about 40 pics of 30kb is loads in 228 ms and the score on tools.pingdom is 92/100 I tried cloudflare before and didn't get these awesome results

I love it!! Thank you for making it possible

This is an excellent plugin and has increased my page load speed. However, Yview does not recognise Shift8 as a CDN provider as yet! Hence only 4 stars at the moment. Hopefully, this will change very soon. If Yview recognises Shift8 CDN my evaluation of this plugin will go from 4 to 5 stars immediately... Definitely a must plugin to have and so easy to set up, great work!
