Content Delivery Network (CDN)
A Content Delivery Network (CDN) is a service that disperses your static assets to various server locations around the world. This makes static assets, which are generally large files like images, physically closer to users and therefore faster to download. As a CDN disperses assets across several server locations, the weight of your site is also distributed more effectively during times of high traffic.
WP Engine’s CDN
WP Engine utilizes Cloudflare CDN for the CDN offering that we include with each plan. WP Engine’s finely tuned caching rules will also apply at Cloudflare’s Edge network. This means pages can be served to users around the world faster, sending fewer requests to the WP Engine origin server.
Some of these features include:
- Cloudflare Polish lossless image compression
- WebP image optimization
- Automatic SSL installation
- CDN at Edge – Utilizing no separate URL for CDN assets
Read more about the global CDN network on Cloudflare. (Note: WP Engine does not currently support zones in Mainland China.)
Our modern network is zero configuration, meaning no additional changes are needed to enable the CDN after you have configured your domain to use Advanced Network or GES. By utilizing a custom Cloudflare configuration at Edge, there are no custom URLs to apply, assets are already secured, and image compression is enabled by default. Additionally, both Advanced Network and Global Edge Security include upgraded performance and numerous security improvements by default.
As static files are rarely updated or changed, CDN caches these files for 24 hours by default. To manually purge CDN cache:
- Log in to the User Portal
- Select the environment name
- Open Caching in the secondary menu
- Click Clear Network Caches
