protonvpn at least in EU is offering a free fast server based in NL. I would have a look
I'm done with proton and their services, over hyped stuff, and their free options mediocre with a stretch, I know it's free so I should not expect much but still way below expectations as well as cuts out of the blue. I tried then the pro version and to my surprise a lot of the IP were already on VPN block lists which kind of defeats half of the purpose of it.
FWIW, i experienced IP/VPN block list with some VPN provider i've tried (including mullvad and proton) especially when i choose popular country. I also don't remember seeing any VPN provider that claim they regularly change available IP address for VPN usage to avoid IP/VPN block list.
