The long-running Fediverse group service Guppe (https://a.gup.pe) will shut down on 31st May 2023 if it doesn't receive enough funding to cover its costs:
I just launched a Calckey server, https://BostonSocial.online for no particular reason except I couldn't help myself. It seems to be working fine.
Anyone who is interested in trying it is welcome to join. It's not just for Boston-area folks.
I'm still playing around and tweaking things, and I still need to apply blocks and server limits, and all this type of stuff, but it's fully operational (I think).
Our new Patreon goal every month is $500/m. We need to get the server to a point every month where we are covering the server costs, have some extra money to expand, give back to the open-source community. If there is anything left at the end of the month to buy me a cup of coffee, awesome. But we have to get the server covered.
