The current federation is not built to support a massive number of users all on the same page.
I am hoping for a solution that involves major servers working together to direct a stream of donations into a group project, a super server designed to meet the need during heavy load events.
It'd probably have to be heavily moderated with minimal local activity. The point would be that when major news dropped, the users of different instances would be able to come to a central forum (the superserver) to discuss with the world, and also to any local or subscribed forums to discuss with their people.
Benefitting all of the admins who no longer have to worry about their server crashing, and all the users who can either avoid the superserver or participate in the larger discussion without any impact to their local Lemmy experience.
