Identified

At 2025-06-14 23:13:52 UTC we identified a hard down on the Southern Cross NEXT cable system, but only effecting Sydney to Los Angeles.

A fault was immediately raised with our vendor who identified a line card fault, a cold-reboot did not rectify the issue, a tech has been dispatched we are currently awaiting further updates. We are not expecting an extended outage.

Customers will experience a higher latency during this time. Traffic has been rerouted via alternative paths, namely via Auckland to Los Angeles via the same cable system.
