Network Pulse

On June 11, 2026, a M5.5 earthquake occurred approximately 58 km south of Sarangani, Philippines. Our monitoring currently shows no active alerts on the network but has identified one latency anomaly.

The affected submarine cables with landing points within 350km include Apricot, Asia Connect Cable-1 (ACC-1), Bifrost, and SEA-US, all landing at Davao, Philippines, which are approximately 246km from the earthquake's epicenter. Latency measurements show an average increase of about 140ms for Apricot, 181ms for ACC-1, 203ms for Bifrost, and 201ms for SEA-US over a period of seven days. These figures reflect potential impacts on network performance but do not indicate any active damage or outages.

On June 10, 2026, a M4.6 earthquake occurred approximately 25 km ENE of Sibolga, Indonesia.

The affected submarine cables within 350km include SeaMeWe-5 and the Indonesia Global Gateway (IGG) System, both landing at Dumai, Indonesia, which are 276km from the event. Our latency measurements show that SeaMeWe-5 has an average latency of ~252ms with 5 checks per week, while the IGG System has an average latency of ~78ms with 30 checks per week. No active alerts have been triggered, and there is no evidence of damage or significant impact on these cables based on current monitoring.

On June 10, 2026, a magnitude 5 earthquake struck approximately 21 km southwest of Balangonan, Philippines. This event is located within 350km of several submarine cables, including the Apricot, Asia Connect Cable-1 (ACC-1), Bifrost, and SEA-US cables, which all land at Davao, Philippines.

Our latency monitoring indicates that these cables have experienced minor anomalies. Specifically, the average latency for the Apricot cable has increased by approximately 139ms over a period of seven days, while ACC-1 shows an increase of about 179ms. The Bifrost and SEA-US cables have seen increases of around 202ms and 201ms respectively. No active alerts are currently in place, indicating that the impact on these cables is minimal.

A magnitude 4.71 earthquake occurred on June 10, 2026, approximately 23 km east of Pāpa‘ikou, Hawaii. The seismic event is located within a radius of 350km from several submarine cables that serve the Hawaiian Islands.

Our monitoring indicates latency anomalies for the Southern Cross Cable Network (SCCN), which has a landing point at Spencer Beach, HI, approximately 103 km from the earthquake's epicenter. The average latency increase measured is around 172ms with about 56 checks over seven days. Other cables in the vicinity, such as the Hawaiian Islands Fiber Link (HIFL) and Hawaii Inter-Island Cable System (HICS), are not actively monitored but could potentially be affected based on their proximity to the earthquake. For now, no active alerts have been triggered for these or other nearby submarine cables.

On June 9, 2026, a M5.1 earthquake occurred approximately 6 km SSW of Sibagat, Philippines. This event is located within a radius of 350km from several submarine cable landing points in the region.

• The PLDT Domestic Fiber Optic Network (DFON) and Submarine Cable in the Philippines (SCiP), both landing at Butuan City, are not actively measured but are close to the epicenter.
• The Converge Domestic Submarine Cable Network (CDSCN), Philippine Domestic Submarine Cable Network (PDSCN), Apricot, Asia Connect Cable-1 (ACC-1), Bifrost, and SEA-US cables all land within 188km of the earthquake's location. Our latency measurements for these cables show that while there are currently no reported anomalies, some cables like ACC-1 have experienced average delays of around 139ms with 169 checks over seven days.

On June 9, 2026, a M5.1 earthquake occurred approximately 10 km north of Sarangani, Philippines. Our monitoring currently shows no active alerts on the network but has identified one latency anomaly.

The submarine cables in the affected region include Apricot, ACC-1, Bifrost, and SEA-US, all landing within 350km of the earthquake's epicenter at Davao, Philippines. Latency measurements for these cables show average delays of approximately 148ms to 202ms with varying check frequencies over a seven-day period. No significant damage has been reported or detected as of now.

A magnitude 5.3 earthquake occurred on June 8, 2026, approximately 19 km SSW of Lumatil, Philippines.

Our monitoring indicates that four submarine cables with landing points within 350km of the epicenter are experiencing latency anomalies: Apricot (Davao), Asia Connect Cable-1 (ACC-1) (Davao), Bifrost (Davao), and SEA-US (Davao). The average latencies for these cables have increased, with measured values ranging from 143ms to 201ms over a seven-day period. No active alerts are currently in place, but we continue to monitor the situation closely.

On June 8, 2026, a magnitude 5.5 earthquake struck approximately 12 km southwest of Balangonan, Philippines. Our network monitoring has identified two latency anomalies and one active alert on our submarine cable systems.

The earthquakes affected several cables with landing points within 350 kilometers of the epicenter. Specifically, the Apricot, Asia Connect Cable-1 (ACC-1), Bifrost, and SEA-US cables, all landing at Davao, Philippines, have shown latency increases: average delays of approximately 143ms, 169ms, 201ms, and 195ms respectively over the past week. The Palapa Ring Middle cable, which lands in Tahuna, Indonesia, is not currently being actively monitored for this event. Similarly, the PLDT Domestic Fiber Optic Network (DFON) and Converge Domestic Submarine Cable Network (CDSCN), both landing at Cagayan de Oro, Philippines, as well as the Philippine Domestic Submarine Cable Network (PDSCN), are also not being actively measured.
