Optus has apologised for a second service outage in less than a fortnight. The issue involved a mobile phone tower - one of 9000 across Australia - in Dapto, a suburb of Wollongong, NSW. Earlier this month, a botched firewall update blocked 600 Triple-0 calls from Optus customers in SA, WA and the NT and was linked to four deaths, including an eight-week-old baby. #Optus #outage #apology #Dapto #phone | 7NEWS Sydney
