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.
There is really not much to discuss. The server was overloaded so we got a bigger one. And there is no reason to mess with stuff like kubernetes when a single server works fine. After all our job is to improve the Lemmy software for everyone, not build a huge centralized platform only on lemmy.ml.
