I run their act binary on one of my servers. Can’t remember much of the setup, so I can’t be too bad. I did have to change the used images though, but I guess that comes with maintenance of you own runner anyway.

I’m using gitea which has CI compatible to GitHub actions with my own runner. It’s pretty straightforward to set up and didn’t give me any headaches yet. It’s a very small instance just for my ownaybe dozen projects though.

Do you have a source for this? I checked https://www.bbc.com/news/articles/c5ypxnnyg7jo but cannot find this.

Edit: https://discuss.tchncs.de/comment/17517599 says that some countries are not included in tariffs because they are sanctioned instead.
