mstdn.starnix.network is one of the many independent Mastodon servers you can use to participate in the fediverse.
Starnix is a Fediverse/ActivityPub Focused platform. Topics are mainly Technology and computer related but are not required to fall into those categories.
Want? You can run it on 1 Gig fine for a single instance but you'll need to eventually tune your mrfs to drop hellthreads or other activities that cause DDoS for smaller instances.
