Its now running on a dedicated server with 6 cores/12 threads and 32 gb ram. I hope this will be enough for the near future. Nevertheless, new users should still prefer to signup on other instances.
This server is financed from donations to the Lemmy project. If you want to support it, please consider donating.
I would love a social network powered by the users that are using it. Maybe also running something like serverless functions on the client devices.
You might want to check the Earthstar project: https://earthstar-project.org/ They are working on that. Right now, it’s super early; they are building the foundations. Peer-to-peer is unfortunately much more difficult to code then servers, because less people have built the building-blocks required, and because mobile phones are actively making it hard to run peer-to-peer apps.
