Hi Qui, For pure routing - If Telstra removed it correctly , and the new provider added it correctly straight away, It should only be as long for the routing tables to propagate and update - ~30 seconds. Without knowing the details of the cutover procedure, the 2 hours may be required for OSS systems to update network, or DNS ttl to expire or other factors. 2 hours time-frame may also be given as a worst case to give enough time to fix any errors.
