An update, some of you might remember we had federation issues with Lemmy.world. For a long time now we have had a second server in Finland that Lemmy.world was pointed at, then that server would pass the activities in bulk to our Lemmy.nz server in NZ. This has worked for a long time to prevent a delay federating all the Lemmy.world content.
A recent version of Lemmy added a way to send activities in parallel. Lemmy.world has turned this on, and not long ago this morning have started sending the activities directly to the Lemmy.nz server again, bypassing the extra one.
Let me know if you see anything strange, but it does seem to be working from what I've seen monitoring it this morning.
