In summary, the location at which an IP egresses Cloudflare network has nothing to do with the geo-ip mapping of that IP. In some cases the decision on where to egress is optimised for "location closest to the user", but this is also not always true.
And then there is the Internet. Often some country (say Iran) egresses from a totally different place (like Frankfurt) due to geopolitics and just location of cables.
So, there is a dashboard internally for that. When we do ProbeNet PoP assessment, we have a high-level overview of the frequent and favored connections. We have a ton of servers in Africa, and there is a strong routing bias towards France, Germany, and the UK instead of neighboring connections.
Everyone in our engineering and leadership is very close with various CDN companies. We do echo this idea to them. It is not IP geolocation; we actually have a ton of routing data they can use.
