Repairs to the Indigo West subsea cable have failed to bring traffic back, according to an update published by Australian internet provider Aus Internet on 16 September. The cable links Perth and Singapore.
The provider says restoration work finished on 15 September, but subsequent testing identified a full cut where a shunt fault had initially been reported. It says a restoration window of 2–9 October is under review. Those dates should not be treated as a confirmed return to service.
What you need to know
If an overseas game or work service feels unusually slow, check with your internet provider before replacing your router or upgrading your plan. This report alone cannot establish whether your connection is affected.
What the update does—and does not—tell us
Aus Internet first logged the outage on 8 August, saying protected services and internet traffic would use alternative routes. We checked the page on 18 September; its latest incident-specific update was still dated 16 September.
The notice relays information from an upstream provider. It does not establish a nationwide NBN outage, identify every affected retailer or give a customer count. We have not independently inspected the cable damage.
Why an undersea cable matters to your home connection
INDIGO is part of the infrastructure carrying data between Australia and Asia. Superloop describes a cable system connecting Singapore to Perth and Perth to Sydney. Your connection to the house is only one part of the journey to a server overseas.
Think of it as having a clear driveway while the road to your destination has a diversion. You can still leave home; the trip may take longer. For internet traffic, the result depends on the alternative path and the networks involved.
A good download result can miss the problem
Latency is the delay while data travels across a network. It is different from how much data your connection can transfer. Distance and the equipment along the route both contribute to that delay.
A speed test to a nearby server does not measure the same journey as a connection to Singapore. A healthy local result therefore cannot rule out a problem reaching a particular overseas service. That is a networking inference, not a measurement we have taken during this outage.
This distinction matters before spending money. Paying for a faster plan does not guarantee lower latency to the server you need.
What to send your provider if something feels wrong
Our practical suggestion is to keep the report specific: name the affected app or game, the server region if it is displayed, when the issue began, and whether other services work normally. Include the time and server used for any speed test, rather than sending only its download number.
If you can, compare the same service over Ethernet to help separate a Wi-Fi issue from a wider connection problem. Ask your provider whether it has an international routing incident affecting that destination. These are suggested checks; we have not reproduced the fault on a customer service.
Avoid making several settings changes at once. Keeping a simple before-and-after record gives support something useful to investigate and makes it easier to undo a change that did not help.
