Emergency Triple Zero call services and mobile Telstra services in at least four states were hit by intermittent “interruptions” early on 4 May after a cable was damaged by fire -- likely caused by a lightning strike -- in regional NSW.
Telstra said in a statement posted online that a cable break caused by an unknown party between Orange and Bathurst in NSW at 2.05AM on 4 May caused intermittent mobile voice connection interruptions in NSW, Victoria, South Australia and Queensland.
“Routers impacted by the cable cut were restored about 4.50AM today,” Telstra said. “A Telstra fibre repair crew has been dispatched. There are still intermittent interruptions to E000 [Triple Zero] calls in NSW, Victoria and WA.
“We are working closely with emergency services in those states,” the telco said.
NSW Police took to social media at 5:44AM warning residents in affected areas that there had been intermittent problems with Triple Zero emergency call services.
At 7:27AM on 4 May, the telco said on social media that a fibre repair crew was on site at a cable pit east of Orange, reporting significant fire damage consistent with lightning strike.
"We're working to restore services ASAP and are sorry for service interruptions. Current impact mostly in NSW and some interruptions in VIC, SA and WA," Telstra said in the post.
The service disruptions come just days after Telstra was hit by another partial partial network outage, with 4G voice calls in various areas around the country affected by the service disruption on 1 May.
A spokesperson for the company said at the time that the issue was caused by technical changes made ahead of upgrades to mobile traffic control equipment in Telstra’s Exhibition Street exchange in Melbourne.
Just a day later, on 2 May, fellow telecommunications provider iiNet found itself scrambling to restore internet services for customers after some of its services and tools were disconnected due to power problems at a data centre in Western Australia.
“Due to loss of power to a data centre in WA, multiple services and tools are currently disconnected,” iiNet said in a post on social media at the time. “We do not have an ETA at this stage, however engineers are currently onsite and working to restore services as soon as possible. Thanks for your patience.”
An iiNet representative told ARN that, as at around 12:20PM on 2 May, the company’s network teams had confirmed that internet traffic and services had been restored.
Update: At about 1:30PM on 4 May, NSW Police took to social media to inform residents in the affected areas that Triple Zero services were back up.
"The restoration of the cable in NSW has been completed. E000 services are returning to normal. We are working with emergency services and our government and enterprise customers to manage any residual issues. We are deeply sorry for the interruptions," Telstra said on its website.
