You can make it as reliable as you want by hosting it on prem.

> as reliable as you want

We self-host GitLab but the team owning it is having hard time scaling it. From my understanding talking to them, the design of gitaly makes it very hard to scale it beyond certain repo size and # of pushes per day (for reference: our repos are GBs in size, ~1M commits, hundreds of merges per day)

Flashbacks to me pushing hard for GitLab self hosting a few months ago. The rest of the team did not feel the lift was worth it.

I utterly hate being at the mercy of a third party with an after thought of a "status page" to stare at.
