Update on service disruption affecting the Australia Singapore Cable

Update: 25 Sept 2026, 05:45 pm AEST

Vocus continues to progress restoration and repair activities following the Australia Singapore Cable (ASC) fault.

 Layer 2 Ethernet services restored via the Perth to Singapore path through Jakarta remain operational, and Internet traffic continues to be managed across alternate paths where this delivers the best customer experience. Traffic originating from Perth on ASC towards Port Hedland, Christmas Island and Anyer, Indonesia remains stable and operational.

Temporary restoration measures remain in place for affected services between Australia and Singapore. We continue to work with partners in Jakarta to manage intermittent instability associated with third-party network infrastructure.

The new 100G path between Japan and Guam is in service, providing additional capacity to support Internet traffic into Asia and Europe and reducing reliance on longer alternate paths. This additional capacity further strengthens the temporary restoration arrangements in place while the permanent ASC repair progresses.

Testing completed from the Perth and Singapore landing stations continues to indicate a cable break within Indonesian waters, approximately 615 km from the Singapore landing station.

Restoring services remains our highest priority, and Vocus continues to work closely with our marine repair partner and relevant authorities to progress the repair program.

As previously noted, Vocus agreed to sequence the repair of Indigo West ahead of ASC to provide the best overall restoration outcome for customers. Repairing ASC requires the affected section of the system to be powered down, which would temporarily remove capacity currently supporting restored services via Jakarta and place additional demand on alternate Internet paths. Restoring Indigo West first provides an additional diverse path between Australia and Asia, allowing affected customer services and Internet traffic to be rerouted before ASC is taken offline for its permanent repair.

Planning for the marine repair operation continues. The repair vessel will depart Singapore on 11 October, and the Indigo West repair is expected to be completed around 24 October. The vessel is then expected to transit to the ASC repair location, with marine repair activities for ASC planned to start around 25 October.

Based on the current repair schedule, completion of the ASC repair remains targeted for 4 November.

Additional contingency has been incorporated into the marine program should conditions affect the planned repair activities. A key dependency of the repair remains completion of the required Indonesian operational permits and clearances. Documentation and approval activities are progressing with the relevant authorities and are part of the pre-repair program.

Subsea cable repairs are complex and remain subject to a number of factors outside Vocus' direct control. The current schedule is dependent on permitting and regulatory approvals, completion of the preceding Indigo West repair, vessel movements, local sea and weather conditions, and the condition of the cable once recovered. While every effort will be made to complete the work within the planned timeframe, these dates may change if operational conditions require.

Vocus will continue to closely monitor temporary restoration paths and available international capacity while the marine repair program progresses, and will provide further updates as key milestones are reached.

Vocus continues to progress restoration and repair activities following the Australia Singapore Cable (ASC) fault.

Layer 2 Ethernet services restored via the Perth to Singapore path through Jakarta remain operational, and Internet traffic continues to be managed across alternate paths where this delivers the best customer experience. Traffic originating from Perth on ASC towards Port Hedland, Christmas Island and Anyer, Indonesia is stable and operational. Temporary restoration measures remain in place for affected services between Australia and Singapore.

We continue to work with partners in Jakarta to resolve intermittent instability with third-party network infrastructure. A new 100G path between Japan and Guam is now operational, providing further capacity to support Internet traffic into Asia and Europe and reduce reliance on longer alternate paths.  

Over the past week, additional testing was completed from both the Perth and Singapore landing stations. These results indicate a cable break within Indonesian waters, approximately 615 km from the Singapore landing station.

Restoring services remains our highest priority. We continue to work closely with our marine repair partner and other stakeholders to finalise the repair program.

Under the applicable repair arrangements, the ASC fault has priority for repair. However, following assessment of the available restoration options and their potential customer impact, Vocus has agreed to sequence the repair of Indigo West ahead of ASC.

This sequencing provides the best overall restoration outcome for customers. Repairing ASC requires the affected section of the system to be powered down, which would temporarily remove capacity currently supporting restored services via Jakarta and place additional demand on alternate Internet paths. Restoring Indigo West first provides an additional diverse path between Australia and Asia, allowing affected customer services and Internet traffic to be rerouted before ASC is taken offline for its permanent repair.

While this approach extends the timeframe for permanent restoration of ASC, it significantly reduces the risk of further customer disruption during the repair program and provides greater network resilience throughout the works.

Our current expectation is for Indigo West to be restored on 24 October, followed by completion of repairs to ASC on 4 November.

Subsea cable repairs are complex and can be affected by several factors. These estimated repair dates remain dependent on local sea and weather conditions, vessel operations, permitting requirements and the exact nature of the repair work. While every effort will be made to complete the work within these timeframes, the dates may change if conditions require.

We will continue to provide updates as repair scheduling and restoration activities progress.
