They are doing their best, but the users can help by spreading out to smaller instances. It's also much better for the fediverse as a whole to have many smaller instances instead of a few giant ones.
Maybe you want to join http://lemmy.today? It's located in Oregon (western USA) and is literally never down. I know since I'm addicted to Lemmy and I'm on it all the time now... :)
Also who doesnt like that cute little Lemmy icon it has. :) Looks like a very surprised lemming, or very happy one...
So far it hasn't attracted any bad behavior and the admin is a super nice guy. Works in tech (of course, who doesn't here, right? ).
I think it's not a major selling point either, just a bit of "open for all until we get actual problems".
There was some guy from exploding heads trying to get users to his instance however. They don't seem very nice at all, and seemingly blocked by a lot of instances.
He is more than open to having several admins :) He is a Linux devops guy who is doing consulting in the area. It makes sense to have several admins due to the "bus factor" or what we shall call it.
Just have to find someone willing to help out. You know anyone?
I have like four different instances I'm using with accounts on each. I'm not sure the best route but feel like I should only have one or two accounts. Probably will keep the four for now just to see which instances seem most reliable. I'll try and keep this one in the back of my mind in case I need another instance though :)
In my experience lemmy.world and reddthat go down a decent amount, especially the latter.
