We have pretty basic needs - git repos + actions - and a bit of downtime here and there doesn't really affect us too much because we're not constantly committing and deploying, but even we're looking around for alternatives now.

Also, looks like people might be pummelling the SourceHut servers looking for an alternative: https://sr.ht/ is down. (Edit: was down when I wrote that, back up now).

tangled.org maybe?
