Where do I find a list of local instances? - Lemmy.world

I wasn’t sure where to ask so I chose here. The other day I saw a post encouraging people to spread the load on lemmy.world and jump onto other instances. I’ve decided to take one for the tea and do it even though my account is like 2 weeks old 🫡 However, how do I find physically local instances? In the post mentioned above someone gave a link that shows some sort of a map(?) where such information could be found. Could someone hook me up with it please?

How can I find out what comments are the replies on? - Lemmy.world

I am loving the app but the only thing that I am missing or not sure how to do is to find out what particular comment a reply is refering too. I used to use Infinity for Reddit and you could click on the reply to see individual comment thread that this reply was related to.
