perhaps a good time to reconsider depending on a third party for your important services to deploy?
Yes, but these decisions aren't under me plus setting up a github kind of thing is way too time consuming with all the features that we're used to now.
Understandable, but surely the potential disruption if github was to go down for a long time or indefinitely would be more than setting up a local git server that you control?
A GitLab droplet on Digital Ocean should run you only $10/month and literally sets up in ~10 min.
What makes the servers of digital ocean safer than github?
They're not GitHub. i.e. The chance of GitHub and your GitLab instance on DO going down simultaneously is very slim. Spend an extra $10/month and you can set up another DO server in another data-center, and reduce the odds of simultaneous failure even further.
Then you've just shifted the problem from GitHub being down to a VPS you've spent 10 minutes maintaining being down.
Maybe now would be a good time to point out the downsides of that decision to whoever made it.
Setting up a GitHub alternative is quite expensive but if you're just making your deployment system more robust it doesn't need to be more time consuming as having a server which you can SSH to.
It is likely that GH have a better uptime than the parent's services.
It is likely that the parent's services would be up while GH is down.
