How to easily check which poll handled the request?

As in the topic - is there a clear and easy way to recognize which poll/node in Cloudflare’s load balancer handled the request?

Anything? Of course I can do it by checking app logs but wondering if it’s possible in a more human way - by checking cookies, headers or anything else?

Do you mean the datacenter serving the request? has colo= which tells you.

Alternatively, in the response headers is cf-ray which has the code appended to it.

Why then both values are different?
On my website in response headers I see “-VIE” which is Vienna (Austria) I guess.
But on there is “colo=WAW” which is Warsaw (Poland).
