Vodafone has suffered another major outage. A telco expert explains what went wrong

Vodafone Australia suffered a major nationwide outage today that may have affected millions of customers.

Customers of Australia’s third-largest telecommunications company in Darwin, Melbourne, Sydney, Brisbane, Perth and Canberra reported having no service for several hours early this morning.

At roughly 11am, Vodafone, which is owned by TPG Telecom, issued a statement saying it was aware customers were experiencing “intermittent issues” with its network. It said the issue “has been isolated and resolved, and services are now being progressively restored”.

However, many people online were still reporting problems with the network hours later.

What caused the outage?

In its statement, Vodafone said “the disruption was caused by a power outage at one of our network hubs”.

A power outage, though it seems unthinkable in an era when you would expect backup power and batteries to be installed in all key facilities, could cause equipment and systems to go offline, malfunction or fail.

The nationwide nature of the outage suggests the Vodafone network includes a centralised “core network”.

The impact of a fault at a “single point of failure” in a centralised core network could cause a cascading infrastructure and system failure. This would ultimately result in a national outage.

In a decentralised telecommunications network, a failure at one facility would cause the network traffic to be automatically switched through to an alternative facility. This improves the network’s resilience.

Vodafone recommended customers restart their phones to restore the network connection. But according to several online reports, this did not fix the problem.

This incident comes a month after Vodafone launched a major marketing campaign featuring US comedian Ali Wong. The campaign claims the company offers better value and coverage than one of its major competitors, Telstra.

Speaking to The Australian in March about the campaign and Vodafone’s promising future, TPG’s chief marketing officer Bec Darley said:

Any previous network issues no longer exist.

A spokesperson for Vodafone told The Conversation the company is “reviewing this incident and working to strengthen the resilience of our network to help prevent a recurrence”.

Too many national outages

There have been several other major telecommunications outages in recent years. These outages aren’t just an inconvenience. They can disrupt businesses and threaten public safety.

In September 2025, an Optus outage that affected people’s ability to call emergency services was linked to the death of two people.

Vodafone also suffered major network issues in 2021, 2016, 2012, 2011 and 2010.

Making matters worse for Vodafone this time around is the fact its own network status checker failed as well.

Vodafone’s ‘network status checker’ also suffered an outage.

The Vodafone spokesperson told The Conversation the status checker page “is supported by some of the systems hosted at the same network hub that was impacted by the power issue, which is why it was temporarily unavailable”.

Much has been said recently about telecommunications companies needing to provide timely and factual information to consumers.

The Australian Communications and Media Authority, in its role as the telecommunications regulator, has taken steps to provide stronger consumer protections during telecommunications outages.

For example, in April last year, the authority set new rules to ensure telecommunications customers are better informed during network outages.

The message isn’t getting through

In its most recent update, Australia’s Telecommunications Industry Ombudsman reported a 5.7% increase in consumer complaints over the past quarter.

This latest national telecommunications outage will be a major test for federal communications minister Anika Wells as well as the Australian Communications and Media Authority.

An announcement of an independent inquiry should be expected in coming days.

A power outage should not take down a national telecommunications network. The independent inquiry should fully report on Vodafone’s network design and where the single point of failures are.

It should also examine what can be done to improve reliability and resiliency.

It seems the message the federal government and the Australian Communications and Media Authority have been trying to impart to the telcos is not getting through.
