If any instance uses anything akin to cloudflare, Google, a cloud provider or a CDN then this question makes no sense because it's "hosted" all over the world.
Not that it ever made any sense because why would it matter where a website is hosted if it's equally accessible globally? It's not like you have to type a longer URL to hit it from Europe lmfao, and It's not like the internet is some sort of local US thing where you have to hear about it by word of mouth.
Also, why would it matter in what country an instance is hosted in? I cant just assume everyone on midwest.social is german because the instance is hosted in germany
The word world is literally in the name… When I joined lemmy I started there because I assumed it would be a general instance. It’s like worldnews where 90% of posts are US politics. Also, it’s not an obsession, most times it comes up it’s just a joke (like this meme).
