Internet users in Pakistan may experience slower browsing speeds and occasional disruptions as Pakistan Telecommunication Company Limited (PTCL) has announced scheduled maintenance work on one of the country’s key submarine cable systems. The telecom operator stated that the repair activity will begin around 11 am Pakistan Standard Time on Tuesday to fix a faulty repeater, a vital component that helps amplify signals along the undersea cable. The operation is expected to last up to 18 hours, during which users may notice service degradation or intermittent connectivity, particularly affecting international web traffic.
In a statement issued on Monday, PTCL said it regrets the inconvenience caused and appreciates customers’ patience during the maintenance period. The company assured that alternate arrangements have been made to reroute traffic through other available systems to minimize disruption. However, users may still experience slower access to international websites, reduced streaming quality, and delays in certain online services. Telecom officials added that normal connectivity is expected to be restored once the repeater repair and testing process is completed late Tuesday or early Wednesday.
Submarine cables are the backbone of Pakistan’s internet infrastructure, carrying the majority of the country’s international bandwidth. These fiber-optic cables connect Pakistan to major global internet hubs through multiple systems, including SEA-ME-WE 4, SEA-ME-WE 5, IMEWE, AAE-1, and PEACE. Disruptions or maintenance activities on any of these networks often lead to noticeable slowdowns, especially in high-traffic services like video streaming, cloud-based applications, and online gaming. Industry experts note that while Pakistan’s growing reliance on international data routes has improved redundancy, the system remains vulnerable to delays during maintenance operations.
According to PTCL, the ongoing work is part of a pre-emptive maintenance plan aimed at ensuring long-term network stability and preventing unexpected service outages. The telecom provider emphasized that such scheduled repairs are essential to sustain the reliability of Pakistan’s connectivity infrastructure. Over the years, the country has witnessed several similar disruptions due to faults in undersea cables, with major slowdowns recorded in 2021 and 2023. These maintenance activities, though temporarily inconvenient, play a crucial role in maintaining the resilience of the internet backbone that supports millions of users and businesses nationwide.
