The second stage Falcon engine appears to have suffered some insulation degradation and loss. It develops just above the bell, on the right-hand side of the motor image in the video. After second stage shutdown, a vapor emission is visible just above the site of the degradation (at the very end of the video). Was this a normal venting, or a non-catastrophic failure of the second stage engine? Congratulations, SpaceX, on designing such a robust engine!
