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?

Thank you for all the compliments.

This ride reminds me of Mastodon.world in November. Details on that are here: https://blog.mastodon.world/and-then-november-happened

So I started lemmy.world on a 2CPU/4GB VPS. Keeping an eye on the performance. Soon I decided to double that. And after the first few thousand of users joined, doubled it again to 8CPU/16GB. That also was the max I could for that VPS type.

But, already I saw some donations come in, without really asking. That reminded me of the willingness to donate on Mastodon, which allowed me to easily pay for a very powerful server for mastodon.world, one of the reasons it grew so fast. Other (large) servers crashed and closed registrations, I (mainly) didn't.

So, I decided to buy the same large server (32cpu/64threads with 128GB RAM) as for masto (but that masto one has double the RAM). With the post announcing that, I also mentioned the donation possibilities. That brought a lot of donations immediately, already funding this server for at least 2 months. (To the anonymous person donating $100 : wow!).

Now next: to solve the issue with post slowness. That's probably a database issue.

And again: migration took 4 minutes downtime, and that could have been less if I wasn't eating pizza at the same time. So if any server wants to migrate: please do! If you have the userbase, you'll get the donations for it. Contact me if you have questions.

is it a good idea to host on my home internet ?

[โ€“] [email protected] 3 points 1 year ago

I bet you could do it if your instance didn't pull in a lot of traffic.

If it did..... I reckon that you might be able to pull it off to a certain extent so long as your internet package was good enough, but if you got hit with a Reddit-level flood of incoming users, your network almost certainly wouldn't be able to keep up.

Even if it could, if you were consistently eating through all the upload bandwidth, I reckon you'd draw the eyes of your ISP and they might send you a letter kindly and respectfully telling you that if you don't upgrade to a commercial line they're not renewing your contract.
