I managed to download the 7B and 13B models; from 30B onwards the URL did suddenly not work anymore, but only returned "Forbidden" (even for the 7B now)...

HTTP request sent, awaiting response... 403 Forbidden

Is this a temporary thing? Is this some kind of traffic threshold on the cloudfront side?
