Submarine Cable Fault PTA Update Internet Pakistan — A undersea fibre-optic cable resting on the ocean floor — the quiet, unseen link that keeps Pakistan connected to the rest of the world.

Submarine Cable Fault Pakistan Fixed, Internet Fully Back

How a Submarine Cable Fault in Pakistan Disrupted Internet Access Nationwide

By Desk Assistant Last updated Jul 3, 2026

The submarine cable fault Pakistan internet users struggled with for days has finally been fixed. The Pakistan Telecommunication Authority (PTA) says internet services across the country are now running smoothly again.

The trouble started when engineers found a fault along the SEA-ME-WE 5 (SMW5) undersea cable route. This cable carries a huge chunk of Pakistan’s international internet traffic, so any damage to it tends to ripple across the whole country.

Many users had already noticed the signs. Pages loaded slowly, video calls froze, and some apps simply refused to connect. The PTA later confirmed what people were feeling wasn’t just bad luck — it was a real technical fault.

In a statement, the regulator said some users could expect uneven service while the issue was being sorted out. Not everyone was affected equally, but enough people felt it for the story to make headlines.

Behind the scenes, Transworld Associates (TWA) worked closely with the SMW5 Consortium to figure out exactly what went wrong and how long repairs would take. Getting a clear repair timeline for undersea cables isn’t always simple, since the fault sits deep below the ocean.

While the fix was underway, PTA rerouted traffic through other international links. This kept most services running, even if speeds weren’t perfect for everyone.

By Friday, the authority confirmed the job was done. Internet traffic has returned to normal, and the earlier slowdowns should now be a thing of the past.

This isn’t the first time weak infrastructure has been blamed for Pakistan’s internet troubles. Back in May, IT Minister Shaza Fatima Khawaja told the National Assembly that frequent power outages were a major reason behind poor telecom service across the country. She pointed to unreliable electricity, heavy reliance on solar backup during shorter winter days, and tough terrain that slows down repair crews.

Fibre theft, cable cuts, and security concerns in certain areas have added to the challenge, she said.

Still, there’s been real progress too. Pakistan now has three submarine cables linking it internationally, and home fibre connections have jumped from 1.9 million in 2024 to 5.1 million within just two years.
