NBN Outage Checker: Check Status in Your Area Now

When your internet cuts out, the first thing most Australians wonder is whether it’s just their connection or a wider problem. Checking an NBN outage checker takes the guesswork out of that moment — and it takes about 30 seconds. In this guide, you’ll find the official tools, the most useful third-party options, and what to do if your area is clear but your connection still isn’t working.

This table summarises the key attributes of Australia’s NBN infrastructure for quick reference.

What does NBN stand for?

NBN stands for the National Broadband Network — Australia’s government-owned wholesale broadband infrastructure. It is not the same as Wi-Fi. Where Wi-Fi is the wireless signal your router broadcasts inside your home, NBN is the fixed-line network that brings internet into your premises from the street. Understanding this distinction matters because NBN outages affect the physical line feeding your home, while Wi-Fi issues typically stem from your router or internal wiring.

Australia’s NBN rollout connected over 12 million premises across multiple technology types — including fibre-to-the-premises (FTTP), fibre-to-the-node (FTTN), hybrid fibre-coaxial (HFC), and fixed wireless or satellite for remote areas. Depending on your technology type, your experience during an outage can vary significantly. Fixed wireless and Sky Muster satellite connections, for instance, may be affected by weather in ways that HFC connections are not.

How do I check if NBN is working in my area?

The most authoritative place to start is the NBN Co network status checker, available at nbnco.com.au/support/network-status. This page displays location-specific outages and planned maintenance — information that carries more weight than community-reported indicators.

Use the official nbnco network status page

Navigate to the NBN Co network status page and enter your full address or postcode. Click “Check Address” to see whether there is an active outage or an upcoming maintenance window affecting your location. According to Superloop’s guide, the checker will return current outages or planned works tied specifically to your address.

Check for planned maintenance

If the checker returns no active issues, look for any scheduled maintenance windows listed for your area. Planned works are often listed days or weeks in advance. NewSprout aggregates both planned and unplanned outages with a 10-day forward forecast, which can be useful if you need to plan around a known maintenance window.

Use ISP-specific status pages

Some internet service providers offer their own postcode-based outage checkers. iiNet provides a postcode entry tool specifically for its NBN customers, and More Telecom redirects users to the NBN Co site with full address entry. If you are with a provider not offering an outage tool, the official NBN Co page remains your best first step.

How to tell if NBN is not working?

There are three practical ways to determine whether the NBN itself is the source of your problem: check your hardware, check other devices, and cross-reference with outage tracking platforms.

Check NBN box lights

Your NBN connection box has indicator lights that communicate its status. Specific light colors indicate power, sync, or alarm states — and these patterns are documented in the equipment guide that came with your installation. A solid green light typically means the connection is healthy; amber or flashing lights usually indicate a problem in progress. If all lights are off, the first step is confirming power to the unit itself.

Test connection on other devices

Try connecting a laptop directly to your router with an ethernet cable. If the connection works on the wired device but not over Wi-Fi, the issue is likely your router or its wireless configuration — not the NBN line itself. This simple test can save you an unnecessary support call.

Use outage detectors

Downdetector Australia aggregates real-time user reports of NBN service problems and outages, showing whether other customers in your area are filing similar complaints. Aussie Service Down takes this further with a live outage map that displays real-time status across Australian service providers — useful for confirming whether a neighbourhood-level event is underway.

What causes an NBN outage?

Planned maintenance and unforeseen incidents are the two primary causes of NBN outages, according to NBN Co. Beyond these, there are several other contributing factors worth understanding.

Planned maintenance

NBN Co periodically schedules maintenance windows during which services may be temporarily interrupted. These windows are typically planned and communicated in advance via the NBN Co website and sometimes through your ISP directly. NewSprout’s database covers both planned and unplanned outages up to 10 days ahead, giving you visibility into scheduled works that might affect your connection.

Unforeseen incidents

Hardware failures, cable damage, power outages affecting network nodes, or extreme weather events can all trigger unplanned NBN outages. In some cases, these incidents affect only a specific node or neighbourhood, while in others they can cascade across a wider area. The NBN Co status page will display these as active incidents once they are confirmed.

Provider-specific issues

Not every service interruption originates with the NBN network itself. Issues within your ISP’s own infrastructure — such as a at their exchange or a configuration error — can present as an NBN outage even when the NBN network itself is functioning normally. Regional Tech Hub aggregates outage information for major Australian telcos including NBN, Telstra, and Optus, which can help you determine whether the problem is provider-specific. Tangerine Telecom offers an interactive map with real-time updates on reported outages across the NBN network, powered by wholesale provider Vocus Pty Ltd. Belong provides information about major, significant local, and other outages affecting its customer areas.

What color should lights be on a NBN box?

NBN connection boxes use indicator lights to communicate their status. While specific light patterns can vary by device model, general conventions apply across most installations.

Normal light status

A solid green light on the NBN box generally indicates a healthy, synced connection. The specific meanings vary — some boxes use amber for power-on followed by green for sync, while others use different color sequences. The equipment guide that came with your installation or the NBN Co support documentation provides the definitive reference for your specific device model.

Troubleshooting abnormal lights

If the power light is off, check that the power cable is firmly connected and the outlet is working. If the sync light is flashing and never stabilises, there may be a line fault between your premises and the node. In cases where all lights are off after confirming power, a hardware fault is likely — contact your ISP for a replacement unit.

For persistent sync or alarm light states, NBN Co’s own support documentation and your ISP’s troubleshooting guides offer step-by-step diagnostics tailored to your connection technology type.

How to check Telstra NBN outage?

If you are a Telstra customer on the NBN, checking for a Telstra-specific outage is straightforward. Telstra maintains a service status page that covers both its own network and NBN-reported outages affecting its customers.

Enter your service address or sign in to your Telstra account to view any active outages in your area. Telstra also publishes major outage information via its support channels and social media accounts during significant events. For a broader view, the Regional Tech Hub aggregates outage information for major Australian telcos including Telstra alongside NBN and Optus, making it a convenient one-stop reference.

If Telstra reports no issue but you still have no connection, the fault may be with the underlying NBN network or individual to your premises — and the NBN Co status checker should be your next step.

If there is no NBN network outage detected at your address and you are still experiencing an issue with your service, please contact your internet service provider as there may be a fault impacting your individual service.

Our status page only shows NBN network outages in your area, not a single service fault impacting one home or an outage within your provider’s network. If no outage is shown but you still have no connection, contact your ISP.

For Australian NBN users, the choice between tools comes down to what you need to find out. The official NBN Co checker is the definitive source for network-level outages — use it first. Third-party trackers like Downdetector and Aussie Service Down fill a complementary role by surfacing user-reported problems that may not yet be on NBN Co’s radar. Together, these tools give you a fast, reliable path from “is it just me?” to “here is the situation.”
