It also stated that other means of providing users with uninterrupted internet services will be considered in order to meet capacity needs and restore full functionality as soon as possible. Internet access will be available as usual across the country.
The Pakistan Telecommunication Authority (PTA) has reported an SMW4 malfunction for the second time in six months, following a similar fault that impacted internet speeds across Pakistan in February.
SMW4 is a submarine cable that connects Singapore, Malaysia, Thailand, Bangladesh, India, Sri Lanka, Pakistan, the United Arab Emirates, Saudi Arabia, Egypt, Italy, Tunisia, Algeria, and France. It is approximately 18,800 kilometers long.
The cable system is made up of two fiber pairs with a design capacity of 1.28 terabits per second which was increased to 4.6 terabits per second in 2015.
