Hi. we have our website fully on Cloudflare pages and workers. We found an option Tiered Cache. We are discussing if we need it. In my understanding such a solution of having the pages near the visitors of the website is already part of Cloudflare Pages, as the static content is deployed over Cloudflares worldwide network, so there is no need of Tiered cache. Tiered cache seems only be interesting for websites we have their origin outside of cloudflare. Am I correct?
