Is outbound federation a known issue?
I've just tested inbound from sh.itjust.works and it was instantaneous. But my outbound posts that have worked take hours and none have succeeded for days.

I dunno. Can't see any of that in Lemmy. So I'll have to test if it's our outbound or sh.it's inbound.

Understood. I'm not just trying to get content to sh.itjust.works, though. outbound from here to .ml, kbin, and fedia have all failed. I'll test kbin inbound.

kbin is not instantaneous. It has not appeared and I assume, due to instability, is likely lost. If it comes through I will update with time.
