Federation with lemmy.world seems luck-based at this point.

I mean, it seems pretty obvious the problem is .world let all these tiny instances that can't even get 500 user a month federate...

But .world now has to serve them up every post from the other tiny instances whose user post to .world because no one is on their home instance.

I highly recommend any such tiny instances mutually defederate from .world, because the tiny instances are what's causing the problem.

Unfortunately they don't want to do that because they'll be cut off from the majority of Lemmy, instead they usually want to bitch and complain and demand .world treats them as the special unique people they truly are.

It's like back in the day when people would make huge posts about leaving social media on social media and the never leave...

If you want to go, just go.

Most people will never even notice

Edit:

To be clear, what causes delays and issues with federations and .world is the sheer amount of instances they federate with.

The two options to fix it is upgrading infrastructure which costs money, or pruning federation until infrastructure has been scaled up.

There's just nothing else that can be done.
