How is lemmyworld so stable? (monero.house)

At the time of writing, Lemmyworld has the second highest number of active users (compared to all lemmy instances)

https://lemmy.fediverse.observer/list

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?

As someone "in the business", but not nearly as technical as you... How far can a single instance scale? Can a load balancer spread it over mulitple front-ends to handle user load? Can the back-end be re-worked to handle hundreds of millions of user operations per second? Can it work with a CDN? Can a single "Lemmy.World" site exist as a distributed site - with hundreds of servers spread across dozens of sites across the globe?

I expect this entire line of thought is antithetical to the entire Lemmy philosophy of distributed operation. I expect that the "correct" way is to spin off "NA.Lemmy.World", EMEA. Lemmy.World", APAC.Lemmy.World", etc. as separate servers. Is that correct?

Thanks.

Best would be to have thousands of servers. I wouldn't make them subdomains of lemmy.world, but people could create separate instances for large communities, for example. https://lemmy-selfhosted.com Scaling: if the Lemmy software gets tuned a bit better, I think the current server could host at least a million users. But let's hope for more servers first...
