Latest information we've got is this:
"Hi! We made some changes on the Free plan to improve connection speed:
We've added new free servers in Romania and Poland (on top of the US, Netherlands and Japan).
Now, you are auto-connected to the fastest server available by default (which is preferred by 99% of users).
Load balancing formula has been improved.
The default connection will give you the best experience available. You can, however, choose to change to another randomly allocated server.
If you want to access country-specific content, we recommend checking out our paid plans, where you can choose between 70+ countries: https://protonvpn.com/pricing. Our free VPN has no ads, no logs, and is as secure & private as our paid plans. It's made possible thanks to the support from our paid users, NOT your data. With that in mind, certain features are necessarily available only on our paid plans."
