 - The migration of CyberCash merchants to the VeriSign Payflow service is
 - scheduled for completion in mid-February. At that time we will begin the
 - shutdown of the CyberCash payment gateway and all related systems. This
 - final shutdown process requires us to change DNS for the VeriSign Payflow
 - service. The DNS change is scheduled at approximately 6PM ET on February 28,
