jrollans.com is a Fediverse instance that uses the ActivityPub protocol. In other words, users at this host can communicate with people that use software like Mastodon, Pleroma, Friendica, etc. all around the world.
This server runs the snac software and there is no automatic sign-up process.
Like on resources. I can run this on a potato if I want and it would still run great (I'm not, but I could*.)
After the mastodon.social DDOS I thought it would be a good idea to have my own instance, so I installed #snac2. It is indeed light and fast, but unfortunately I found some operational bugs that stopped me from getting the most out of it. So now I'm trying #gotosocial. I'm giving my contacts a bit of a rollercoaster, but I guess you have to break eggs to make an omlette.
