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.
Bonfire just instituted a “Federated” flag in their alpha. I think this could be useful.
This is already in nightly, you can see it on the test instance here https://voyager.lemmy.ml/c/photography@lemmy.ml
Make sure you visit in a browser aince apps wouldn’t have implemented an in development feature.
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.
PieFed does this.
How does this work anyway, and does it match with Lemmy’s approach?
I noticed crust was saying my dev instance was not federating anymore, which was neat. It was because I don’t leave my dev instance online all the time 😁
It looks like this - https://piefed.social/c/adultswim@lemm.ee
Thanks, I mean, how does this work in the backend?
Oh :)
Once per day a request is made all instances to retrieve the list of their admins. If that request fails then they’re flagged as ‘dormant’. If dormant for 5 days, flagged as ‘gone forever’ and then PieFed doesn’t try to federate with them again and all their communities have that warning on them.
If any Activity arrives from a dormant / gone instance then it’s restored to full operation.
