Sopuli is having a federation issue, where outgoing data is failing to federate. You can post to the communities there, but content is failing to federate to other instances out from sopuli, meaning almost no-one is getting to see sopuli-related posts and comments. (Only sopuli and whatever instance the content originates at, few others)
This post currently has triple the votes over on sopuli, and a comment by me from my sopuli account, all of which aren't syncing back to lemmy.world
Noticing the same. Sopuli seems to have recovered, and is now syncing up, though slowly.
Votes and really new posts and comments are still out of sync. As of writing this, my comment made on this post, using my sopuli account, still isn't on lemmy.world.
