Adobe public repo is down?

We just rec'd this as the root cause of the issue:

Root Cause : The original issue appeared to be with NGINX web-server which had to be restarted to fix the issue however the root cause of the repeated downtime was due to expired certificates causing repeated error messages and filled up the disk space on the server.

Does anyone there know why this keeps going down?   We've asked for root cause through our Adobe support ticket, but we've yet to get an answer.

Team is working on it. I will keep you posted once it is up and running.

Its down and we reported it to the team. We hope it will be fixed soon. See the featured thread for more updates.
