Can confirm - a comment I made to a lemmy.world community around an hour ago hasn't shown up on that server yet.
Edit to add: looks like this post correlates with when I was logged out of my session, and I see we're on a newer version than before. Probably something not quite right from the upgrade?
Acttually the issue with outbound federation not properly working is from before they upgraded to 0.19.0-rc4, but 0.19.X made it even worse, because it breaks various clients, e. g. Jerboa, due to some breaking API changes it introduces.
To me it looks like outbound federation is working again, e. g. posts I create on lemmy.sdf.org are now federated again to the (original) community on lemmy.wtf.
@SDF Same here!. It loosk like lemmy.sdf.org does not do outgoing federation to certain instances. In my case it stopped federating posts, comments and votes to lemmy.wtf. I found the following issue on github which explains how outgoing federation will stop, when another instance is considered dead and not marked alive again due to a scheduled task not running:
@SDF Looks like it's happening again. Outbound federation stopped. I have tested this from two other lemmy instances. I can still pull comments from lemmy.sdf.org via search, but neither posts/comments nor votes are actively pushed out.
Which means that lemmy.sdf.org is in a bubble. Nobody hears us. Can you please look into this and/or state whether you are intending to maintain this lemmy instance or not.
We are also readying another release candidate 0.19.0-rc.4. As usual it is available for testing on voyager.lemmy.ml and by installing the Docker image on your server. There are no breaking changes this time as we are preparing for the final release. It has been one month since we announced the major breaking changes for 0.19. In that sense we would like to know from developers of Lemmy clients and frontends if their projects are ready for 0.19, as we are planning to release it within the next weeks. There is no specific release date, but we will first update lemmy.ml to a release candidate, and if it works well publish the new release shortly after.
I didn't get the impresssion that frontend and client devs have signaled that they were ready for a backend update to 0.19.X. And consequently lemmy.ml is still on 0.18.5.
