Similar to Mastodon's spikes last year, it seems. Anyways, there is data to think about. Source
My biggest issue is that at least two out of three times I go to browse/post/comment on lemmy.world, the server is down. I have no clue the actual up time, maybe I am just unlucky. But I am considering migrating my main account to another server.
My alt's server has never experienced this much issue. Hopefully the devs add a migrate function.
