As it stands right now, it looks like we have to just judge based off of how old posts are to see if we can still interact with a community.
You mean like if there’s a community called
!cats@example.comand your home instance no longer federates with the instanceexample.com?If so, I’ll add that to Tesseract as it sounds useful.
This is already in nightly, you can see it on the test instance here https://voyager.lemmy.ml/c/photography@lemmy.ml
The best tool I know of is the Federation Checker, but something like it should definitely should be built into clients.
Notably, Beehaw is defederated from .world and sh.itjust.works, while dbzer0, quokk.au, and anarchist.nexus are defederated from feddit.org.
That’s a handy tool, thanks for posting it. Do you happen to know how the lists are sorted? It’s not alphabetical.
Not sure how; it’s also not by defederation date, otherwise feddit.org would be at or near the bottom of the list for dbzer0.
I feel like there should be an “are you alive” federation activity in activitypub, as well as an “I’m back” activity.
Servers go up and down enough that maybe it should be part of the spec
A heartbeat activity! Or maybe a ping.
I like it! Maybe I’ll write an FEP for it, lol.
