CIRA has shared the followed explanation for today’s cancelled TBR session;
I would like to provide you an update about the cancellation of today’s TBR session.
We have identified that the technical difficulties were caused by a data synchronization issue with the TBR servers, which prevented all Registrars from logging in. As a result, there were no successful TBR connections or requests during the September 24, 2014 session. The problem has now been corrected.
The TBR list from the September 24, 2014 session will be rolled over to the next TBR session, to be held as scheduled on October 1st, 2014. The complete list is available at tbr.cira.ca
If you have any questions or concerns, please do not hesitate to contact CIRA.
