Thanks to CTOnews.com netizens for their unfinished thoughts and Karamazov's clue delivery! CTOnews.com, November 8 (Xinhua)-- Optus, Australia's second-largest telecom operator, suffered a massive network failure on November 8, local time, leaving about 10 million users unable to use the Internet and phone services, accounting for 40 percent of Australia's total population.

The failure of Tuyuan Pexels caused traffic delays, a large number of small businesses were unable to use the mobile payment services provided by Optus, and dozens of hospitals were unable to answer emergency calls. The failure occurred at 4 a.m. local time and the service did not come online again until 18:00 in the evening.

A preliminary investigation revealed that the failure was not caused by a hacker attack, which the company blamed on a "network technical glitch" and said it needed more time to investigate the specific cause.

CTOnews.com noted that just over a year ago, Optus suffered the worst data breach in Australian history, in which the personal data of more than 9 million customers was stolen.
