The submarine cable network remains stable with no anomalies detected over the past 24 hours from 4157 latency checks across 650 cables. The network is performing optimally and all critical systems are functioning without issue.
On June 4, 2026, a M4.9 earthquake occurred 70 km southwest of Modisi, Indonesia. While several cables with landing points within 350km of the epicenter were affected, our latency measurements indicate that they continue to operate normally and show no impact from the seismic event. The network is robust and continues to provide reliable service.
M4.5 earthquake · 88 km W of Manokwari, Indonesia
The network remains stable with 4226 latency checks conducted over the last 24 hours across 650 submarine cables, detecting no anomalies or active alerts. This indicates a consistent and reliable global connection.
A recent seismic event on June 4, 2026, near Manokwari, Indonesia (M4.5 earthquake, 88 km west), did not impact the submarine cables in the vicinity. The Palapa Ring East cable, which has a landing point within 350km of the event, is operating normally as indicated by our latency measurements, showing no changes from baseline performance.
M4.9 earthquake · 58 km NNE of Labuan Bajo, Indonesia
On June 3, 2026, a magnitude 4.9 earthquake struck approximately 58 km NNE of Labuan Bajo, Indonesia.
