There is no CDN.
Yes, it’s true. There is no CDN. Currently there are these static pages served by a Nginx container and a PowerDNS infrastructure running on two nodes of four-node Docker cluster. It’s a kind of experimental installation regarding to all these nice technologies and buzzwords like Docker, cluster, cloud-native, Kubernetes, CDN and so on.
