In a statement, the Pakistan Telecommunication Authority said due to a fault in the international submarine cable, internet services have been affected. “Since evening, some areas of Pakistan have experienced a disruption in services,” it said, adding that PTCL, along with international organisations, are working to ascertain the location where the fault has developed. The Pakistan International Airlines (PIA) also tweeted about an outage in the check-in systems of the airline across the country due to the fault in the international submarine cable. “PTCL network is down due to damage to their underground cables causing outage of PIA Check-In systems across the country. We’re moving to backup systems & manual processes. We regret the inconvenience caused to our passengers due to the resulting delays,” tweeted the airline.
