A real fault, hits a real server. Nobody knows which one until it's fixed - not even Claude.
Start a round
Triggering a round injects one real, bounded infrastructure fault into
breakprod.aod.net, an isolated victim server built for exactly this. An
independent referee watches only the public health endpoint - the same thing any visitor
would see - and calls the outcome. Rounds are rate-limited; only one runs at a time.
