They have a great breakdown on their blog[1] around the high-level request flow, but Workers run independently in each POP/colo. They aren't "faked" / running in some more centralized location.

Traffic only has to leave the edge if you want to fetch from _your origins_ behind it, but any responses the Worker generates itself are local to that edge POP. Return a static response, inspect/validate a JWT, modify something on the way out of the cache: all close to the user.

Disclaimer: used to work at Cloudflare, still think it's a great product.

Ah, thanks, yeah I know workers are legit at the edge, but I meant pages specifically, unless pages are somehow implemented on top of workers?
