SYDNEY (Reuters) -Australia's second-largest telco, Optus, had no crisis plan when a network-wide outage left nearly half the country without phone or internet for 12 hours, an executive told parliament on Friday, acknowledging the company's defences had failed.
The Singapore Telecommunications-owned company had recently war-gamed scenarios in which the routers that direct voice and internet data failed in entire states, but it never expected a nationwide shutdown because it had alternate connections built into its network.
