This isn't going through the Wikimedia CDN network. It's on wikimedia cloud services, which is a free computing infrastructure (OpenStack/K8s) for community members to build community maintained tooling for Wikimedia.
Still think this is a nice idea in theory. In practice I often vendor stuff like this, meaning I just don't use CDNs and deploy "local" copies. I could write a few pages about why this is a bad idea, but there are also some advantages.
I'm wondering a bit about your new zealand redirect, as there is no colocation site in new zealand on that map at least.
