As of 6.30pm this evening, some Telstra customers in Sydney and Melbourne are reportedly unable to make calls or access the internet using Telstra’s post-paid service. The issue does not appear to be affecting all customers; indeed, our Telstra post-paid service appears to be working in the Hornsby, New South Wales area, but there are reports of an outage in our area regardless.

Telstra blamed human error for a major national outage last month, when an engineer accidentally switched off a core network node, causing chaos across Telstra’s network. Earlier this month, around half a million pre-paid customers also experienced issues, and it wasn’t just Telstra, but its MVNO partners as well.

A Telstra spokesperson told the Sydney Morning Herald:

“We are aware of an issue affecting some of our mobile customers who are having difficulty making and receiving calls, and using data. We are looking into the cause of this issue and apologise for the inconvenience this is causing. We are doing everything we can to restore services as soon as possible.”

We’ll keep an eye on the service status reports and let you know if we hear anything further.
