I did a search from shitjustworks for “reddit die” and did not find https://lemmy.world/c/watchredditdie so I made https://sh.itjust.works/c/watchredditdie (unnecessarily). This should really not happen. When someone makes a community there should be a “ping” sent out to notify all other federated instances.
And from what I know, if I post to !sh.itjust.works/c/watchredditdie only users on sh.itjust.works will see the posts until other people from other instances randomly come across it somehow and subscribe? This really needs to be improved.
The community you’re trying to subscribe to only has one post, and I believe that post may predate your instance spinning up.
It’s not really a good example of federation on Lemmy, because it doesn’t have content to federate.
Even your ping idea wouldn’t have worked here
Why not? When the person created the sub it would have sent out a ping to all federated instances, and thus when any account on a federated instance searches the keyword they would find that sub. IE: each instance would have a list of subs of all other federated instances. Like a sitemap.
As I said, I think the only post in the community you were looking at was made before your instance was up and running and able to be pinged
