Vocus, the cable's owner, reported a break on the Australia Singapore Cable between Anyer (Indonesia) and Singapore on 4 September. Vocus says the fault is in Indonesian waters, about 615 km from the Singapore landing station, and expects repairs to be completed on 4 November, after INDIGO-West is restored.
With INDIGO-West also out of service, both direct Perth–Singapore cables are down. Reports say traffic has been rerouted over other systems, including paths via Australia's east coast and the United States. Vocus restored Layer 2 Ethernet services on 11 September over an additional Singapore–Jakarta path.
Vocus: ASC repair to start around 25 Oct, completion targeted for 4 Nov
Vocus says testing from the Perth and Singapore landing stations places the break in Indonesian waters, about 615 km from the Singapore landing station. Vocus agreed to repair INDIGO-West first, because repairing ASC means powering down the section now carrying restored services via Jakarta. The repair vessel is due to leave Singapore on 11 October, finish INDIGO-West around 24 October, then start the ASC repair around 25 October. Vocus is targeting completion on 4 November, depending on Indonesian permits, weather and the cable's condition.

Vocus says the break is in Indonesian waters.
Repair expected to be completed on 4 November
Vocus has agreed to sequence the INDIGO-West repair ahead of ASC, which it says gives the best overall restoration outcome.
Layer 2 Ethernet services temporarily restored via Jakarta
Vocus says an additional network path between Singapore and Jakarta allowed temporary restoration of Layer 2 Ethernet services.
Both direct Perth–Singapore cables out of service
With INDIGO-West already down, reports say Perth–Singapore traffic is taking longer routes, including via the United States.

“We observed short flaps occurring on the ASC submarine cable system at 04/09/2026 03:50:33 UTC. However a hard down event followed at 04/09/2026 06:19:12 UTC Due to the Indigo West cable system also being offline for shunt fault repairs, traffic will take a longer path which will result in higher latency between Australia and Singapore.”

From coastal AIS receivers (aisstream.io, Fintraffic, Norwegian Coastal Administration). A ship near a fault isn’t necessarily working on it; the repair ship is named only when a source says so.
Shown for context. An earthquake or storm nearby is only given as the cause when a source says so, and outage signals show connectivity dropped somewhere in a country, not which cable.
