Best instance to create your user on? - Lemmy.world

There’s been some downtime on Lemmy.World. I think this wont be the last time, as the amount of users coming in during the next month will be ginormous. That’s completely fine with me. However, during that time, I couldn’t use the Fediverse because my access to the Fediverse comtes through logging in through my Lemmy.World user. (please correct me if I’m mistaken…) So I get that Fediverse is decentralized. Anyone can create their own instances. Which is the most reliable? Only time will tell? Or will this be made differently in the future?
