Regarding GitHub SaaS service, where are thier servers hosted? Also, can we choose the region where our SaaS services will be hosted?
GitHub.com is hosted on GitHub-owned servers in co-location facilities in the United States
One of the features of GitHub AE when available in 2Q 2021, will be data locality, that means some choices of location (Azure region).
But this is more of a dedicated(private) offering and hosted on github.com, at premium cost etc.
