The activity on here and their Youtube is pretty much dead. Which is interesting, because their Twitter appears to be active somewhat. It is indeed strange that their site is down. I mean, I don't really play Aether II anymore for several reasons, but I just thought this would be worthy of note to anyone still watching this thread.
one their facebook they mentioned knowing the site is down and are trying to fix it and in that message and on twitter they linked to minecraft.curseforge.com/projects/the-aether-ii to download it there
EDIT: and mentioned 1.12.2 so in theory it might be released as alpha or beta within a month (they said a week about 3 weeks ago, with the link and fixing the site in a reply to someone on facebook, id assume the site is priority as its most known way to get it)
I'm not sure if this is just me but I can't access aetherii.com at all through any browser.
I tried google chrome and firefox. I can ping it just fine in my terminal window. I am using cloudflare's DNS service 18.104.22.168 thing... is that an issue lol?
aetherii.com doesn't exist anymore, it's been in development hell forever. You can go to the curseforge page for Aether II and join the discord however, that's where all the activity is. There's also the Gilded Games twitter you can follow for updates.
The curseforge page is here. If you want to suggest something to the Aether devs join the discord server at the bottom if you have discord, but if it's to add the Aether to the PS4 edition it's not happening, Mojang and the Aether devs don't work together and Mojang will never add the Aether.
