Telstra mobile services experienced a widespread network outage on Tuesday affecting customers across the country. The network failure affected calls and data services, including 2G, 3G and 4G services, as well as SMS and online alerts for people residing in the bushfire-prone zone of Western Australia. However, the telecommunication company confirmed that all services have been restored following complaints from the users.

Customers took to social media to vent out their frustrations. Telstra issued a formal statement saying it was investigating the problem.

“We are working to resolve the issue as quickly as possible and thank customers for their patience,” the statement said, as quoted by the ABC.

The SMS and online warning systems for the residents of the Myalup fire zone were down, according to the Department of Fire and Emergency Services in Western Australia. However, the department said that landlines were working.

“Whilst the mobile network is down, the text warning system is not achievable but landlines, however, can still receive phone calls under the telephone warning system,” the ABC quoted DFES South West Superintendent Ricky Curtis as saying. “The second issue is that the internet access is also compromised, so the ability to get current information from places like the DFES website and others is compromised.”

Sydney, Brisbane and Melbourne had the largest cluster of service faults. Some regions also experienced issues listed for ADSL lines.

The outage affected a large number of businesses and individuals. However, Telstra has not yet disclosed the reason behind such a massive disruption of services.

“We are aware of an issue currently affecting mobile voice and data nationally,” the Sydney Morning Herald quoted Telstra NSW media manager David Taylor as saying.

Even though the social media is inundated with complaints from disgruntled customers, the problem was not absolute as some customers still had access to call and data services.
