A New Global Debugging Challenge Launching Today

Argentina and Spain played the World Cup Final. Today, you’re on call.

A goal is overturned by VAR, but the live scoreboard keeps counting it.

No outage. No errors. Just the wrong score in front of millions of people.

We turned it into a production debugging challenge for developers: The Goal That Stuck.

You can use any tools or AI agents you want.

The obvious fix may solve the incident, but it might not survive deployment.

Think you can find the real bug?

the "you can use any AI agent you want but the obvious fix might not survive deployment" framing is a good hook, most coding challenges reward the fast fix not the correct one. curious how you're grading it though - is there a hidden test suite that catches the shallow patch, or is the scoring more about explaining why the naive fix breaks under load/replay?
