On the second day of play, the courtside scoreboard stood still at 47–47 and later went dark. IBM programmers said it was only programmed to go to 47–47 but would be fixed by the next day.[13] The on-line scoreboard at the official website lasted slightly longer: At 50–50 it was reset to 0–0. Users were asked to "please add 50 to the Isner/Mahut game score". [14] An IBM programmer worked on the computerized scoring system until 11:45 pm to accommodate the match's scores for the next day, although it would have again malfunctioned had the match gone beyond 25 more games.[1
