FWIW, if all you have is a truly static website (html, css, and js), then GitHub Pages is free and you can point a custom domain there from your registrar, and don’t have to worry about backups or server uptime.
I wasn’t aware of the Github pages being free that’s neat. It is fully static (running on nginx but generated with hugo) and I use freedns.afraid.org for the domains. Good to know thanks for the tip :)
