At the time of writing, Lemmyworld has the second highest number of active users (compared to all lemmy instances)
Also at the time of writing, Lemmyworld has >99% uptime.
By comparison, other lemmy instances with as many users as Lemmyworld keep going down.
What optimizations has Lemmyworld made to their hosting configuration that has made it more resilient than other instances’ hosting configurations?

I had issues trying for lemmy.world yesterday, but it worked fine today. I just waited a day because I figured between upgrades and a massive influx of new users it was probably gonna be a bit unstable sometimes.
