Telstra is hit with a massive national outage affecting customers in Australia’s biggest cities 

Telstra has been struck by a massive outage – with several customers complaining about their mobile data isn’t working. 

In a statement, the telco said: ‘We are looking into an issue impacting some Telstra mobile customers nationally.

‘Customers may be experiencing a loss of mobile data services. We are urgently working to resolve the issue’. 

According to the site Downdector, customers of the telco had been experiencing issues since 12.30pm on Wednesday afternoon.

The connectivity issue appears to be affecting internet, phone and Wi-Fi. 

One Twitter user said: ‘It seems like @Telstra are having some sort of mobile data outage in Rose Bay (in Sydney’s east) at the moment so I’ve resorted to connecting to the free Wi-Fi from one of their remaining telephone boxes.’

Complained another: ‘I’m inside Melbourne central shopping mall. Why is the data speed so damn slow?’

‘I haven’t had access for weeks … just inane, useless messages like “Your internet connection has dropped out”,’ a third wrote. 

It is unclear what has caused the latest outage, which appears to be affecting residents from Sydney’s east, northern South Australia and southern Queensland.
