There are various locations where HA documentation exist. We need to consolidate this, and also remove some old pages. - University does not link to the HA AWS guide at https://docs.gitlab.com/ce/university/high-availability/aws/ - University *does* link to https://about.gitlab.com/high-availability, which is extremely outdated. This page should be removed from https://about.gitlab.com and relevant pieces should be consolidated into https://docs.gitlab.com/ce/high-availability. - AWS and other HA guides should be linked from University, and probably cross-linked from the HA docs page. cc/ @axil @seanpackham What do you think? I need to make some updates to these docs so I will try to tackle some of these things.
