Feb 13<\/var>, 02:01<\/var> UTC<\/small>
Resolved<\/strong> – As of approximately 48 hours ago, we can confirm that the Indigo West cable system has been fully restored.<\/p>\n

In further positive news, the submarine cable system connecting Oman to Marseille was also successfully repaired within the last 24 hours, following a prolonged wait of several months for the cable repair vessel to access the restricted affected area.<\/p>\n

While both systems were offline, we proactively provisioned and activated even further capacity between Perth and Asia to maintain service continuity.<\/p>\n

These measures further enhance our network resilience and ensure Western Australia will maintain low-latency connectivity to both Asia and Europe, even in the rare event of multiple concurrent submarine cable faults occurring again.<\/p>\n

Final update from the Indigo Team below, for those interested.<\/p>\n

We are pleased to confirm that all three faults affecting the Indigo West cable system have now been fully repaired and resolved, with services restored and stable.<\/p>\n

A summary of the faults, including their locations and resolution status, is provided below:<\/p>\n

– Fault #1 \u2013 A Fibre break in Indonesian Waters that was successfully repaired on 19\/01\/2026.
– Fault #2 \u2013 A Partial fibre break off the coast of Perth in shallow waters that was confirmed successfully repaired on 10\/02\/2026 at 10:57 UTC.
– Fault #3 \u2013 A shunt fault in Indonesian Waters approximately 380-410km away from Fault #1 location, inland towards Singapore was successfully repaired on 03\/02\/2026.<\/p>\n

All traffic has been restored and services are now operating normally. We will continue to monitor the Indigo West closely to ensure stability and reliability of the network.<\/p>\n

Identified<\/strong> – The Indigo-West submarine cable system went down at 2025-12-03 08:42:14.512953 UTC roughly ~44 hours ago.<\/p>\n

We have now been provided with information we can disclose publicly.<\/p>\n

– OTDR testing indicates that the fault is located between two subsea repeaters, approximately 725 km from Singapore.
– Callout notification to the marine vessel repair company has been issued and a vessel is being organised to conduct the repair. The repair vessel is currently available for approximately mid-January 2026.
– Marine vessel repair company will also begin the permitting application process with the Indonesian authorities which is expected to take approximately 45 days. This would make the repair permit approval ETA ~19th January. <\/p>\n

Traffic has automatically rerouted via alternate paths. Customers in Australia will experience higher latency when accessing Southeast Asia or Europe, and vice-versa.<\/p>\n
