I believe it failed to land successfully. They pretty much avoided covering it in the video IIRC. I was watching the launch videos for the Iridium sattelites where AFAIK there is a single recovery stage for each of the 8 (I think) missions. I saw someone say in the comments that of the 8 missions, the recovery was only successful 5 times. So it's still not perfect, but for the 5x it was, it saves a lot of money.
