It's very nice, and thanks for including all instances. We are supposed to be a network of Lemmy instances working together. This site highlights that idea so thank you.
If I could offer an improvement idea, it would be to first show instances that are down in it's own group, and then every other instance exactly as it's done now, in alphabetical order.
I updated https://lemmy.today this morning and no problems at all.
We are a small instance but still wanted to post this. Maybe it calms the nerves for some instance owners. :)
