Sure, you can use VPN or any other hosting/cloud but in the most cases you have to pay fee. I think a lot of people want something "for free" so that is the reason they use "free" filesharing tools or online disks/clouds.
But why did you say about 90s? I think online disks and cloud storages...
I prefer playing FOnline Reloaded rather than Fallout 76 when it comes to online/multiplayer Fallout. I tried other servers too but I like Reloaded the most. For me this is better "Fallout Online" than this game which Bethesda created.
You should ask someone on http://fonline.ru/forum/index.php
because I don't know. For now, I develop project called FOnline: Tactics and we will make translation in the future too. If you interested in let me know via pm.
