Internet connections from GitLab

Hello there!

We have a GitLab instance (Community Edition 12.8.1) running on AWS EC2 installed using Onmibus and we are in the process of isolating all of our tools (including GitLab) from any kind of Internet connection. We don’t know if GitLab makes any connection over the Internet (some kind of plugin, integrations, etc) and maybe we are not seeing it.
