Could have a self hosted git or ci/cd pipeline for deployments and code access during outages. They don't need to be up constantly, just need to be able to keep a backup of the code somewhere and have some way to run critical deployment scripts if github actions are unavailable
Well these things should be tested and verified periodically, just like ANY backup. You shouldn't just tick the "enable backups" box in AWS and then never actually test them
We've been using gitea since 2019 with no problems. Drone for CI, although these days you can just stick with the built-in "actions". It's always funny reading the news about yet another GitHub outage, when our gitea instance hasn't had a minute of unplanned downtime in 6 years. (And very little of planned downtime, always in non-working hours.)
We use gitlab at my company. the k8s yaml files are a bit complicated but the simpler shell based ones (publishing npm packages, etc.) are pretty straight forward
