Submarine Cable Failures Disrupt Internet in the Philippines

• •Two submarine cables connecting the Philippines to Singapore and Hong Kong failed, cutting 300 Gbps of capacity.
• •The incident caused significant internet slowdowns nationwide, affecting video streaming and calls.
• •The cause of the failure is under investigation, with sabotage being a potential factor.

On October 2, 2026, two submarine cable segments connecting the Philippines to Singapore and Hong Kong failed, resulting in a loss of 300 Gbps of capacity. This incident caused widespread internet slowdowns across the country, affecting users' ability to stream videos and make calls. The Department of Information and Communications Technology is investigating the cause, with sabotage being considered a possibility. Submarine cables, which carry over 99% of intercontinental data traffic, are prone to breaks due to various factors such as anchors and fishing gear. While redundancy measures allowed internet service to continue, users experienced increased latency as traffic was rerouted through longer paths. Repair efforts will take days to weeks, depending on weather conditions and the availability of repair ships. Philippine ISPs had previously secured spare capacity on alternate routes, mitigating the impact of the outages.
