I’ve been here for years and I’m an instance admin and I still don’t really know how the posts go from one website to another. I think it’s the same technology they use to send pokemon to a different game boy
@prehensile this does mean that for a post to appear on another instance, it must disappear from your instance. mastodon's innovation is sending the posts back and forth so fast that you don't notice they're gone
@prehensile Oh you young and naive people! Obviously the instances are connected via Laplink, exchanging information at the speed of light (or at least faster than a null-modem cable)
@prehensile A German dwarf called Eugen reads them all, writes them on the back of an envelope then runs to an internet cafe in Leipzig and posts them everywhere.
@prehensile Glad somebody finally automated the timing of switching the other Gameboy off so they clone properly. Way less headache than trying to do it with a link cable across the aisle of a moving school bus.
