Philippine submarine-cable outage slows internet; PLDT reroutes most affected traffic
International cable disruption affects connections
Internet users in parts of the Philippines experienced slow or intermittent service on Friday, October 2, after providers reported trouble on international submarine-cable links. GMA News said advisories from Converge, PADECO and the University of the Philippines Diliman Network Help Desk described a disrupted cable segment between the Philippines and Singapore. The advisories also reported a problem on a segment linking the Philippines and Hong Kong.
INQUIRER.net separately reported the university help desk’s warning that connections to sites hosted overseas could have higher latency and intermittent performance. It cited PADECO’s notice that the Hong Kong segment affected overall international capacity. The reports describe uneven slowdowns and disconnections, not a complete loss of internet across the country. Neither outlet supplied a verified count of affected customers.
Providers warn customers; linkage varies
The reported cable problem did not affect every carrier in an identical, proven way. INQUIRER.net quoted Globe Telecom as warning that some mobile and broadband customers could see slow access because of a technical issue. Globe did not say in that advisory whether its problem was caused by the same submarine-cable disruption. Manila Bulletin also described the October 2 evening slowdown across multiple providers, citing the network advisories and the reported disruption to international routes.
For users, the immediate distinction is between local access and traffic that depends on overseas capacity. The UP Diliman notice, as reported by INQUIRER.net, specifically flagged offshore-hosted sites as more likely to show higher latency or intermittent responses. That does not establish that every domestic website remained unaffected, or that all subscribers of a named provider had the same experience. Customers should use their own provider’s advisory for the current state of their connection.
PLDT reroutes traffic; cable cause under investigation
In a 9:30 p.m. Philippine-time advisory, PLDT said a Philippines–Singapore submarine-cable cut had affected services nationwide. The company said it had successfully rerouted most, not all, of the affected traffic and expected service to normalize shortly. Rerouting can mitigate a slowdown before a damaged route is fixed; PLDT’s statement did not give a completed physical repair time or verify that every customer’s service had returned to normal.
GMA News reported that the Department of Information and Communications Technology was investigating what caused the disruptions. Secretary Henry Aguda said it was too early to conclude whether the cause involved natural cable damage, equipment failure or sabotage. He said connectivity had not been completely lost and that, at the time of his remarks, there were no reports of critical infrastructure being significantly affected. Those are time-bound statements, not a final incident report or a guarantee against later problems.
What remains unresolved
The source reports do not establish a reliable nationwide customer total, a final cause, a cable-repair completion time or universal restoration. Nor should the separate Singapore and Hong Kong route advisories be treated as proof that one identical failure mechanism affected both. The defensible update is narrower: users in parts of the Philippines faced degraded internet on October 2, carriers responded to reported international capacity problems, and PLDT later reported rerouting most of its affected traffic. Its expectation that service would normalize shortly was a forecast, not an independently verified outcome. The DICT’s statement about critical infrastructure reflected only reports available when its secretary spoke.
