#2Is it just me, or does it seem to be temporarily down?

#3> Should I use AI to solve Advent of Code puzzles? No. If you send a friend to the gym on your behalf, would you expect to get stronger? Advent of Code puzzles are designed to be interesting for humans to solve - no consideration is made for whether AI can or cannot solve a puzzle. If you want practice prompting an AI, there are almost certainly better exercises elsewhere designed with that in mind.
And yet I expect the whole leaderboard to be full of AI submissions...
Edit: No leaderboard this year, nice!

It's up for me (but the first puzzle won't be available until 15 hours from now).

#6Looks like after the AI automation rush last year, the leaderboard has been removed. Makes sense, a little sad that it was needed though.

i don't think there is a global leaderboard this year. just private ones.

Not this time:
> The global leaderboard was one of the largest sources of stress for me, for the infrastructure, and for many users. People took things too seriously, going way outside the spirit of the contest; some people even resorted to things like DDoS attacks. Many people incorrectly concluded that they were somehow worse programmers because their own times didn't compare. What started as a fun feature in 2015 became an ever-growing problem, and so, after ten years of Advent of Code, I removed the global leaderboard.
