Its now running on a dedicated server with 6 cores/12 threads and 32 gb ram. I hope this will be enough for the near future. Nevertheless, new users should still prefer to signup on other instances.
Are there still issues with cross-instance content? Previously, if I signed in to lemmy.ca and subscribed to a channel on .ml, I didn't see all content. Likewise, if I left a comment from my .ca account, it wouldn't necessarily show up for users on .ml.
If this is still a problem, it's a HUGE roadblock in being able to just tell people to join other instances, if we don't want to fracture an existing community.
Edit: That may have simply been a result of the excess load?
Edit 2: Okay I'm testing and it looks like this was just an issue of load; I don't seem to be having any further issues with this.
Edit 3: Comments from users on lemmy.world still don't seem to propagate correctly. I can see them from .ml but not .ca
