I've read that the same tech stack is intended to be used for Lemmy. Given how impressive the performance of the linked site is, it suggests very promising things for when it's implemented.
Just my dev instance.
(comment to use to make me a mod)
Yeah - it's what I use for testing stuff (it's a bit underpowered though: 1 core CPU, 1 GB Ram). I made that comment partly to verify how it would be announced back to me from .world (except I forgot to subscribe first). Anyway, now mastodon.social is aware of me, and is very keen on telling me about accounts that have been deleted (I swear that site has deleted more accounts that could ever have been created).
I looked up lemmy.ml out of interest (I realise you aren't classifying it as generalist). Anyway: it says that the server is in France.
Also, if you're able to lookup by IP instead of URL, you can bypass any CloudFlare confusion, and confirm that LW is hosted in Finland.
The 'trending communities bot' relies on another bot, at lemmyverse.net. That bot is a bit fragile, and hasn't worked for a week: see https://data.lemmyverse.net/
If you follow the GitHub link, you can see the process failing. I'll message the bot's author at some point, unless it automatically rights itself (it often does).
