Pakistan's internet comes from under the sea

Almost all international internet travels through fibre-optic cables lying on the sea floor, not satellites. Here are the cables that connect Pakistan, what happened when two of them were cut, and how to see it all yourself.

02Why the net crawled in September 2025

In early September 2025 two major cables, SeaMeWe-4 and IMEWE, were cut in the Red Sea near Jeddah, Saudi Arabia. Both carry traffic between Pakistan and Europe, so internet slowed across Pakistan and the region until traffic was rerouted and repairs went ahead. Repairing a deep-sea cable needs a special ship and can take days to weeks.

03Good news: SeaMeWe-6

On 22 November 2025 SEA-ME-WE 6 reached Pakistan: 19,200 km, more than 100 Tbps in total, with 13.2 Tbps allocated to Pakistan. More cables on different routes mean one cut hurts less.

04Fun facts

05Net slow? What actually helps

  1. Check if it's everyone: look at your ISP's or PTA's announcements and tech news. If a cable is cut, restarting your router won't fix it.
  2. Use a wired connection or sit close to the router; Wi-Fi loss adds to the problem.
  3. Avoid peak hours for big downloads and updates (evenings are worst).
  4. Keep a backup: mobile data from a different operator can route differently.
  5. Download in advance: lectures, videos and files you need for the next day.
  6. Run a speed test (e.g. fast.com) before complaining to your ISP, and share the result.
