We have received confirmation from the Indigo Team that a cable fault is present on the Indigo West cable system. Their OTDR testing indicates that the fault is located between two subsea repeaters, approximately 725 km from Singapore. The results of OTDR testing are submitted to Indigos Marine Team for assessment. Further updates will be advised as they arrive. Traffic is flowing through alternate routes from Sydney/Guam to Asia and Sydney/US for all other traffic currently. Further route optimisation will be undertaken where available.

Please be informed that the 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. The 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. The ETR has not been shared as of yet, but we will continue to work closely with the Indigo NOC and inform you as soon as it is shared.
