Cyber attack downs Telstra home internet, but there’s a fix

A cyber attacked has brought down Telstra home internet, but luckily there’s a quick fix to get back online.

Telstra has confirmed that a Denial of Service (DoS) attack has impacted its Domain Name Servers (DNS), meaning it’s unable to route internet traffic as usual. Because of the nature of the attack, users may find that their NBN routers display an online connection even though an actual connection to the internet is unavailable.

“We’ve identified the issue and are working on it,” Telstra tweeted. “Some of our Domain Name Servers (DNS) used to route your traffic online are experiencing a cyber attack, known as a Denial of Service (DoS). Your info isn’t at risk. We’re doing all we can to get you back online.”

If you need to get online now, there’s a simple fix while Telstra sorts its issues. While Telstra’s DNS is down, you can change your router over to another DNS provider like Google, Cloudflare or OpenDNS, as follows:

  • Google: and
  • Cloudflare: and
  • OpenDNS: 208.67. 222.222 and 208.67. 220.220

It’s easiest to change your DNS settings from automatic to any of the couples above on your router rather than individual devices. As each router is different, you’ll likely have to Google something like, “change DNS [router name and model]”.

Telstra’s advised you should change your DNS back to automatic and use their own service once the issue has been resolved.
