@TheKinrar Could you explain the sorting of the instances list a bit more clearly?

Specifically, why are the top two instances with 'B' HTTPS and no IPv6 ranked higher than the next two with 'A+' HTTPS and IPv6?

Uptime is nearly the same, and user counts vary somewhat. https://mastodon.network/media/AXjxJTyydcrLoKo5wKU
