SYDNEY (Reuters) - Australian telecoms provider Optus said on Monday that a massive outage which effectively cut off 40% of the country's population and triggered a political firestorm was caused by "changes to routing information" after a "routine software upgrade".
More than 10 million Australians were hit by the 12-hour network blackout at the Singapore Telecommunications-owned telco on Nov. 8, triggering fury and frustration among customers and raising wider concerns about the telecommunications infrastructure.
