Addendum to the previous post:
My music domain glassdoor.net has finally been transferred to the new registrar. The issue was apparently on the destination side. I filed a support request for someone to take a look and it was resolved within 30 minutes. Seems the transfer got stuck at a specific stage of the state machine and would not budge unless someone intervened. All it took was a little prayer to the right deity to undo the latch and let gravity take over.
I had faith in the laws of nature. But it took an irrational belief in supertechnological intervention and a cry to the tech support heavens to heal a broken heart.
