Hello Mark,
That's what happened last weekend: Martin Hannigan and I got the ball rolling on Sunday morning about 1000 EST. Our 24x7 customer service department contacted Dotster and Melbourne IT. Melbourne IT changed the panix.com name servers back to their original settings and transferred the domain back to Dotster.
I can confirm that Verisign did get in touch with our Production Manager (Peter Berry) around 1pm Sunday (New York time), and our Reseller Program Manager (Steve Karabatsos) around 4:30pm Sunday (New York time). We were contacted previously by Panix around 5pm Saturday (New York time). I believe that Verisign complied with all their obligations with respect to the ICANN transfer policy, and Verisign was very cooperative in assisting us with the issue. Regards, Bruce
