Update on routes to Singapore and Southeast Asia
A subsea cable fault is causing higher latency to Singapore, and Neptune has enabled alternative routing through the VPN service to minimise the impact.
James Gemmell, December 07, 2025

A fault has been identified on the Indigo-West submarine cable, one of the major cables connecting Australia to Singapore, and a pathway Neptune customers rely on by nature of our upstream partnerships. We learned from our upstream provider (GSL) that this happened on 3 December, and repairs require a specialised marine vessel and permits from Indonesian authorities.

Resolution schedule
The repair team has shared a tentative schedule:
| Date | Action |
|---|---|
| 5 December 2025 | Repair permits lodged with Indonesian authorities |
| 19 January 2026 | Repair vessel scheduled to mobilise |
| 23–30 January 2026 | Cable repair window |
| 30 January 2026 | Estimated completion |
What this means for you
Your connection is still fully operational, and all traffic is automatically routing through other international paths. You may notice slightly higher latency when accessing services hosted in Singapore, Southeast Asia, or some parts of Europe. Browsing, streaming, and day-to-day use should otherwise be normal.
While repairs are underway
If you rely heavily on low-latency paths to Southeast Asia, we’ve enabled a temporary contingency option through Neptune’s VPN service. This uses our alternate VRF paths to route VPN traffic in a way that will provide more consistent low latency performance during the cable repair.
East Coast
Use VPN tunnel Sydney via Nexthop (ACS route to SIN)

West Coast
We’re working on additional transit for West Coast subscribers and expect this alternative route to be active next week.
If you'd like help setting this up, our team is here to assist. Thanks for your patience while the cable operators complete their repairs. We'll continue to keep you updated as we receive new information.
