will not agree to the implication that the solution is simply to have no large instances.
The instance is already large as it is. Closing down registrations will not reduce the size of the instance. It will just stop it from growing even more and it would give a chance for other instances to help spread the load.
Aside from version updates, I haven't changed my server setup since I set it up months ago, and my instance has only a handful of active users. Only two of them subscribed to !fediverse.
Also, keep in mind that I am receiving updates just fine (maybe with some delay) the problem is that nothing I post on the lemmy.world communities end up visible here.
