How does Cloudflare edge nodes cache?

When Cloudflare caches an asset, does it automatically propagate that asset to all its other CDN edge nodes or does it only cache it to that one CDN edge node?

Since Cloudflare is a:

  1. ReverseProxy CDN, and not a push CDN
  2. Anycast CDN (to the outside)

it will just be cached at the POP it was requested from. So if you request it from Frankfurt (FRA) once, it will be cached there. If you later, for the first time request it from Los Angeles (LAX), it will not be cached there.

Hope that helps :slight_smile:

In addition, Tiered Cache can increase cache hit ratios from nearby datacenters if configured.
