Pakistan on Tuesday held talks with four states whose telecommunications networks will remain suspended for two hours on Wednesday morning during which a key undersea cable that developed a fault on Monday night will be repaired. The world's longest fibre optic link - known as SEA-ME-WE — developed the fault 52 nautical miles (over 96 kilometres) off the coast of Karachi, a senior official of the Pakistan Telecommunication Company (PTCL) confirmed.The breakdown of telecommunications channels badly hit the 100-odd Internet service providers of the country who lost millions of rupees on Tuesday. Bankers complained they were greatly inconvenienced by the shutdown. Online traders suffered losses as the Karachi Stock Exchange and put up a terse notice on its website saying that it could not be updated on a regular basis. "India, Djibouti, Oman and the United Arab Emirates are the four countries whose telecommunication channels will be disturbed while the defective portion of the 39,000-kilometre-long cable is repaired," Mashkoor Hussain, senior executive vice-president (operations) of the PTCL, told Dawn from Islamabad.
