What happens if lemmy.world or any other instance goes down without notice? Then there'd be a void of communities for a while right, or do other instances keep backups of some sort?
Thinking about this now that .world gets tons of attention.
That may be true but I am subscribed to many communities over many instances so I would just post and comment somewhere else. It's not hard to browse the all feed and see where the action currently is.
Spreading out like the fediverse is designed is good. Redundancy and crossposted content is good.
We're seeing the biggest instances struggle with the traffic lately, so I'm just engaging more with different communities whenever they're not accessible.
