Ask HN: How are you storing your personal Git repos?

I am, as I'm sure many of you are, not confident in the integrity of Github, BitBucket etc. when it comes to hosting git repos, in the long term. Censorship, or incompetence could lead to my work being zapped for any number of reasons. During last year, I hosted all my repos on a local machine via Gitea, which then pushes commits on to Github where I keep my repos publicly. I'm sure my paranoia is fairly mid among the community, but I wonder what are you doing about your open source work and how do you store your repos? And is my concern warranted?
