Submarine Cable Fault May Disrupt Pakistan Internet

Submarine Cable Fault May Disrupt Pakistan Internet

Pakistan may face intermittent internet slowdowns after a fault developed in the SEA-ME-WE 5 international submarine cable system, the Pakistan Telecommunication Authority said on Thursday night. The warning is significant for millions of users, businesses, freelancers and digital service providers who depend on stable international connectivity for work, communication and online transactions.

According to the PTA, the authority is closely monitoring disruptions in internet traffic linked to the SMW5 cable fault. The issue could result in temporary degradation of service quality and connectivity, meaning users may experience slower speeds, unstable browsing, interrupted video calls or delays in accessing international platforms.

The telecom regulator said Transworld Associates is coordinating with the SEA-ME-WE 5 consortium to identify the exact cause of the fault and estimate how long restoration may take. The authority added that traffic is being shifted through alternate international links to reduce disruption and keep services running as smoothly as possible.

Customers of Transworld Associates also received messages acknowledging a technical fault in one of the company’s submarine cables. The company apologised for the inconvenience and said its technical teams were working on the matter, with further updates expected as restoration efforts continue.

The development is important because submarine cables carry the bulk of Pakistan’s international internet traffic. Even a partial fault can affect users across multiple networks if backup routes become congested or if international bandwidth has to be redistributed during repair and rerouting operations.

Pakistan has faced similar internet disruption concerns in the past whenever international cable systems developed faults or maintenance work affected capacity. Such incidents usually create visible pressure during peak hours, especially for streaming, cloud platforms, online gaming, financial systems, remote work tools and call-centre operations.

The latest disruption also comes at a time when Pakistan is trying to expand its digital economy, promote freelancing, increase IT exports and improve online public services. Reliable connectivity is no longer only a consumer convenience; it has become part of the country’s economic infrastructure and directly affects productivity.

In November, Pakistan received the SEA-ME-WE 6 submarine cable, a newer high-capacity system designed to strengthen digital resilience and improve connectivity between Southeast Asia, the Middle East and Western Europe. The government has described the newer cable as a major improvement because it provides additional capacity and route diversity for high-traffic regions.

For ordinary users, the immediate impact may vary depending on location, internet service provider and the level of congestion on alternate routes. Some users may notice only brief slowdowns, while others could face unstable connectivity if their provider relies heavily on affected international capacity.

The next step will depend on how quickly technical teams identify and repair the fault. Until then, the PTA is expected to continue coordination with operators and stakeholders while internet providers reroute traffic to protect service continuity as much as possible.
