- A sample BGP replay shows a wrong remote AS corrected, followed by three passing checks in 6:41.
Field notes
The sample replay shows the neighbor stuck in Active until the remote AS is corrected, after which the listed BGP, route, and dataplane checks pass. The page says a first solve earns 100 points while repeats earn 10%, and describes timed jams with a shared outage and leaderboard. It also presents separate school and hiring workflows, including join codes for students and observer terminals for interviews.
