The Accreditation Criteria for Domain Update has been adjusted to check for a response code of 1000.
This change has an effect on registrars that have currently passed the gTLD OT&E.
The previous process for Domain Update included a response code of 1001 on request, followed by a poll message being queued indicating the result of the update.
The new process allows for the Domain Update command to be processed prior to a result code being returned. If the processing was successful, a result code of 1000 will be returned by the sever.
For more information please see the gTLD Domain Update command.
