Similarly, ACC-1 (Asia Connect Cable-1), Bifrost, and SEA-US cables have average latencies of ~224ms, ~270ms, and ~210ms respectively, with the latter two having fewer measurements at 9 and 10 checks per week.
Forest fire in France
The network remains stable with 2552 latency checks conducted across 647 submarine cables over the past 24 hours, detecting no anomalies or active alerts.
A wildfire in France occurred from July 4 to July 6, 2026, affecting an area of 6055 hectares and impacting approximately 3188 people. According to the Global Wildfire Information System (GWIS), this event was assessed with a green alert level, indicating a medium humanitarian impact based on the burned area and affected population.
The submarine cables within our monitored range, including those near Barcelona and Marseille in Spain, are operating normally. Our latency measurements show no changes or impacts from the wildfire event, confirming that all cables are functioning as expected without any reported degradation in performance.
M4.6 earthquake · 185 km W of Abepura, Indonesia
On July 5, 2026, a M4.6 earthquake occurred approximately 185 km west of Abepura, Indonesia. This event is located in an area where several submarine cable systems are known to operate.
We have monitored the Kumul Domestic Submarine Cable System, which has a landing point at Vanimo, Papua New Guinea, about 259 km from the earthquake's epicenter. Our latency measurements indicate that this system experienced average latency of approximately 246 milliseconds over the past week, with 45 checks conducted. No significant anomalies or disruptions have been observed in our monitoring data for any of the cables within the affected region.
M4.5 earthquake · 71 km W of Ovalle, Chile

On July 5, 2026, a magnitude 4.5 earthquake occurred approximately 71 km west of Ovalle, Chile. Our monitoring currently indicates two latency anomalies and one active alert on the network.
