On the eve of Optus chief executive and the telco’s owner Singtel being hauled into the principal’s office – that of federal communications minister Anika Wells – the timing of the weekend’s second network outage is catastrophic. The pair of telco executives, Singtel’s Yuen Kuan Moon and Optus boss Stephen Rue, wouldn’t be relishing the upcoming get-togethers with the premiers of South Australia and Western Australia either. While the latest Optus breakdown, in Dapto, south of Sydney, was limited in scope and without the tragic ramifications that marked the first outage less than two weeks ago, both failures prohibited callers from getting through to emergency services. Pressure is mounting on Optus CEO Stephen Rue after the disastrous outage.
