Internet users across Pakistan are expected to experience slower connectivity for several days as maintenance work is carried out on a key international submarine cable, a critical component of the country’s internet infrastructure. Submarine cables form the backbone of global internet connectivity, linking Pakistan to international data networks, and any maintenance or disruption in these systems can directly impact browsing speeds and service quality nationwide. With a large portion of Pakistan’s internet traffic routed through a limited number of such cables, even routine maintenance can lead to noticeable degradation in performance.
The slowdown is anticipated to last for up to four days, during which users may encounter reduced speeds, higher latency and intermittent disruptions across various online platforms. Such maintenance activities are typically conducted to ensure long term network stability and prevent unexpected outages, but they often require temporary rerouting of traffic through alternative channels. This can lead to congestion on available bandwidth, resulting in slower internet performance for both mobile and fixed broadband users. Past incidents have shown that even partial outages or repairs to submarine cables can significantly affect connectivity across the country.
Telecom operators generally work to minimise the impact by redistributing traffic across other available international links, but capacity constraints can still affect user experience, particularly during peak usage hours. Pakistan relies on multiple submarine cable systems, including those operated by major telecom providers and international consortiums, to maintain connectivity with global networks. However, the limited redundancy in these systems means that maintenance or faults in one cable can place additional strain on others, amplifying the effect on end users.
The situation highlights ongoing challenges in Pakistan’s digital infrastructure, where increasing internet usage continues to put pressure on existing capacity. As reliance on digital services grows across sectors such as banking, education and communication, ensuring stable and high speed connectivity has become increasingly important. While the current slowdown is expected to be temporary, it underscores the need for continued investment in infrastructure, including additional submarine cables and improved network resilience, to support the country’s expanding digital ecosystem.
