On Monday afternoon, the US Open experienced an unexpected interruption when a fire alarm went off in the broadcast building that houses the tournament’s automated line-calling system, known as “Hawk-Eye.” The incident led to a temporary suspension of play across all courts, including Arthur Ashe Stadium and Louis Armstrong Stadium.
With no human line judges available, the alarm triggered an evacuation of the building, causing the Hawk-Eye system to shut down. Chair umpires were forced to halt the matches as confusion spread among players and spectators.
The delay lasted for six minutes before officials determined it was a false alarm. Play resumed shortly thereafter, with an announcement informing fans of the technical issue. The incident occurred during Daniil Medvedev’s fourth-round match against Nuno Borges, leading to a brief but significant pause in the third set.
The USTA later issued a statement confirming that the alarm was only a precautionary measure, allowing the tournament to continue without further disruptions.
