I have excess compute, how can I contribute positively to the Internet?

I have excess compute and bandwidth capacity and thought it would be a great opportunity to contribute positively to the Internet and the broader community. I would like to volunteer those resources towards services/projects/efforts that would be meaningful, or simply fun! (Note: I am NOT soliciting ideas for novel services - though if there is a gap to fill, happy to take a swing). (Another note: I do not have physical gear to give, just what is running at home and some of my time).

Admittedly, I've been in commercialized environments for so long that I am out of touch with what characterized the early web: a more open, community-driven, and less commercialized environment. I only recently heard of the "indie web" and sunk so much time just surfing(!) the web instead of being funneled towards links. That nostalgia motivated me to use my technical skills to do something fulfilling.

(I am purposefully omitting my compute and bandwidth capacity to avoid coloring your expectations or influencing your suggestions. I want to hear your ideas without any preconceived notions about what might be feasible or not. If this thread is ever found by someone with more or less idle compute than me, to be able to contribute as well)
