There seems to be a large amount of spin from the company executives about these outages, but nothing mentioned about the real cause.
CFO Ackland speaks about "good mobile signal strength" being available at certain locations during the outage. However, that radio signal is completely useless if the core / IMS network elements have failed.
The CEO and CFO both said that mobiles camped onto other provider's networks during the outage and that emergency calls would have still been possible.
However, if the customer's own radio (RAN) signal is still active (and core network has failed), mobiles WILL NOT move to other carrier's networks for the purpose of initiating emergency calls.
The company needs to come clean about what really happened to cause the outage.
Moreover, in the current political climate, all risks to network integrity need to be removed. Allowing offshore operation & maintenance access to Australian networks is an unacceptable security risk.
While offshoring may be cheaper, telecommunication companies should re-consider this horrible risk to Australia's critical infrastructure.
