Yup, I just typed in my PSN. The code should be sent to your email.
This might help anyone downloading it, I changed my DNS under the Network settings to Primary: "220.127.116.11" and Secondary: "18.104.22.168". I plugged that in, restarted my PS4, and it went from 16 hours to about 73 minutes. Then again, not sure if it was a coincidence to the restart.....but hey! Worth trying.
