Using Hetzner vSwitch (https://docs.hetzner.com/robot/dedicated-server/network/vswitch/) one can connect nodes across locations and internal traffic (across locations) between them is "free of charge".

Theoretically, one can bootstrap a CDN (with a Hetzner origin) with POPs in SG, FI, US and DE and save quite a bit of transit cost for origin fetchs.
