You have to sign in with a Google account to access the content. All I get is a login page, at least.

Anyone got a link that is publicly accessible?

Worked fine for me too. I think it might do that if you've already been logged into a Google account and signed out. Try deleting your Google cookie(s) entirely.

Works fine for me in incognito mode.
