A scheduled maintenance operation has been planned on one of Pakistan’s key submarine cables to repair a faulty repeater. This critical activity, led by an international cable consortium, will begin on October 14, 2025, around 11:00 AM PST, and may continue for up to 18 hours. The maintenance aims to restore full functionality and strengthen Pakistan’s international internet connectivity.
Importance of Submarine Cable Maintenance
Submarine cables play a vital role in carrying the majority of Pakistan’s international internet traffic. These cables lie deep under the ocean and are equipped with repeaters that amplify data signals across long distances. When one of these repeaters malfunctions, it can affect the stability and performance of data transmission, making timely repair essential for maintaining uninterrupted global connectivity.
Expected Internet Degradation
During the maintenance window, customers across Pakistan may experience temporary Internet service degradation. This could include slower browsing speeds, streaming interruptions, and occasional connection delays. Complete outages are not expected, but slight performance dips might occur during peak usage hours. Internet Service Providers (ISPs) are already working to reroute traffic through alternate submarine cables to minimize disruption.

ISPs have issued public advisories, assuring users that the inconvenience will be temporary and that efforts are being made to ensure a swift return to normal service. Updates will be provided throughout the maintenance window for transparency.
Future Benefits of the Repair
Once the maintenance work is completed, the repaired submarine cable will offer improved stability, faster speeds, and more reliable connectivity. Such proactive measures are part of ongoing efforts to enhance Pakistan’s digital infrastructure. The repair ensures long-term network resilience, supporting growing demands for high-speed internet across the country.
