News Desk January 13, 2022

The Pakistan Telecommunication Authority (PTA) on Thursday said that it had found a fault in the international submarine cable, SMW4, operated by the Pakistan Telecommunication Company Limited (PTCL) in the Indian ocean due to which some internet users may experience downgraded speeds during peak hours.

A statement from the telecommunication authority said that alternate measures to provide uninterrupted internet services to the users have been taken on a priority basis to meet capacity requirements including additional ad hoc bandwidth in the system.

It further said that work is underway to fully restore the internet services at the earliest. "The PTA is monitoring the situation and will continue to update on it," it concluded.
