I am confused on how to sign up for Cloud Services

I have been looking at the page to sing up for the cloud services
but when i follow the link that takes you to nextcloud, i dont see the option to sign up for the Disroot cloud. I go to sign up with a provider, but Disroot is not listed. Am I doing something wrong? Is this service no longer available? Can someone help with step by step information?

Well on that page you link to, right next to login button there is pretty big “Signup for Disroot” button which as name suggests is what you’re looking for.
