SYDNEY, Nov 9 (Reuters) - Australia said on Thursday it would launch an investigation into a 12-hour national outage at telco Optus that cut off internet and phone connections to nearly half of its population, hitting critical services including payments, transport and hospitals.
The federal government would undertake a post-incident review into the outage, Communications Minister Michelle Rowland said, describing its impacts as "particularly concerning."
Australia's media regulator will conduct a separate review into the outage after emergency triple zero ("000") calls went down on Optus landlines, Rowland added.
Optus, owned by Singapore Telecommunications (STEL.SI), has not given the cause for the unprecedented outage, one of the biggest the country has witnessed.
The outage happened 14 months after Optus was hit by one of Australia's biggest cyber breaches.
