@wimleers 2 of those are fastly. I'm going to guess that's a feature they call Shield: https://docs.fastly.com/guides/performance-tuning/shielding. where they route all requests from all their different locations through a single location. Resulting in fewer requests to origin.

I guess the third is then drupal.org's own varnish server, which at this point probably only serves as a load balancer ;)
