Cache miss from different IP addresses

My previous question was closed without being answered.

How can I know how many bandwidth used by Cloudflare from my server?

After some research, I have new developments (new question) on this issue.

My Page Rule Settings:

And I have a few proxy servers for testing CDN caching, includes Hong Kong, Japan, US, etc…

  1. Now I use the Hong Kong proxy server (in other words, use a Hong Kong IP address) to download file at, the cf-cache-status is MISS. Good, this is as expected.
  2. I use the same Hong Kong IP to download app.exe again, the cf-cache-status is HIT. Good, this is as expected, too.
  3. Now I use a Japan IP to download app.exe, the cf-cache-status is MISS. Why? Wasn’t it was cached?

Each colo has it’s own cache. When a cacheable resource is fetched from a colo in Hong Kong, it will be only be cached in the Hong Kong colo. If a visitor connects through a colo in Japan, Cloudflare will still request the resource from your origin. You could enable Tiered Cache to reduce the number of requests that reach your origin.

Forgive my ignorance, what is colo?

Co-Location, a common term to describe a shared hosting facility. A Cloudflare Data Center essentially. Sometimes called a POP (Point of Presence)
