Content Delivery Network (CDN)
All live stores (stores that have the Domain set) have CDN out of the box. It starts running 24 hours after the domain is set.
The Cart plan does not have CDN by default since it's intended for development purposes.
Flush CDN Cache
If you changed images or your CSS is not refreshing with regular Flush Cache, you need to Flush CDN Cache as well. Go to Addons > KeyCDN and click the button.
Some of your images might not load from a CDN
Our system tries to serve images as quickly as possible. In some cases, this means that it will load images concurrently from CDN and your store domain.
