+Wait for the node to appear in tailscale, confirm it to be a legit exit node (step 11), choose it in your client boom! In less than 5 minutes you access the internet from another place.
 Note: Scaling up also reinitializes the existing nodes. Just use the newly created one and delete the old.
 Note: It seems not all fly regions have their own exit routers and some use another for egress traffic. This needs further investigation.
