How to reach GitLabs software repo

Can someone please tell me the URLs/IPs that i need to pass in my Firewall to update Gitlab? The update page found here(https://about.gitlab.com/update/#centos-7) isn’t any help at all and I can’t find this info anywhere else.

I opened up packages.gitlab.com so I can pull the shell script to configure the repo but now it’s timing out on all of the mirrors (which all appear to be S3 addresses).
