Telstra has backed away from claims it has been hit by a cyber attack, after initially saying outages to its internet services had been caused by a third party.
The telco initially said a widespread internet outage was believed to have been caused by a denial of service (DoS) cyber attack, causing significant disruption.
On Twitter, it said home internet connections, including NBN, had been affected.
Telstra said it was working to address the significant internet outage, which had impacted large numbers of users around Australia.
Telstra's own Network Outage internet pages have also been impacted, leaving many affected customers left to learn about the outage through social media.
However once services were back to normal operation, the company posted on Twitter again.
"The massive messaging storm that presented as a denial of service cyber-attack has been investigated by our security teams and we now believe that it was not malicious, but a domain name server issue," the company said.
"We're really sorry for getting in the way of your weekend plans."
