Beta curriculum totally inaccessible. Help!

I am struggling to get access to the beta curriculum. Random success to login up to page 3/3 then the error messages start appearing.
Have cleared caches of Chrome and Safari - no success. (??)

If you’re talking about creating an account, that is disabled on Beta.

Yeah, apparently it’s offline. I can’t access beta either.

It’s been like this for days and it still doesn’t seem to work. You can clone it and use it locally though. You can find the guide here:

I haven’t had any trouble accessing the beta site in the last 5 days.

I am new to coding. How can I start please?
