Similar boat myself too, finished moving all important stuff from GitHub to self-hosted Forgejo with cross-platform builds. Not only do I avoid all the downtime stuff, but E2E builds also takes ~20% of the completion time it used to take, since now my runners have dedicated hardware hosted at home.

We were on self-hosted Gitlab but after a merger were forced to Github. Navigation feels painful in comparison and basic features such as commit graph are now behind more expensive tiers.
