PTCL Warns of Internet Slowdowns Due to Submarine Cable Maintenance

Pakistan Telecommunication Company Limited (PTCL) has issued an important notice for its broadband customers. Starting tomorrow, May 11, 2026, users might experience slow internet speeds. Furthermore, this service degradation will primarily occur during evening hours. The disruption is due to scheduled maintenance activity on one of PTCL’s submarine cables.

The maintenance operations will officially begin tomorrow. Consequently, the repair work will continue for a week, lasting until May 18, 2026. During this period, customers may face noticeable internet service degradation. PTCL shared this update via their official X account and expressed regret for the upcoming inconvenience.

The International Cable Consortium is handling the necessary repair work. Generally, an international cable consortium is a joint group of global telecommunications operators. These organizations invest in, build, and maintain the massive undersea fiber-optic cable networks that carry the world’s internet traffic. In this instance, the consortium will repair a specific fault on the submarine cable connected to Pakistan’s network.

Internet users should brace for slower browsing and downloading speeds over the next week. Specifically, the network degradation will heavily impact evening traffic. Therefore, users who rely on fast internet for evening tasks or entertainment should plan accordingly until the consortium resolves the fault on May 18.
