National Power Grid Fails In Pakistan; Cities Plunge Into Darkness

In the late hours of January 9, several cities of Pakistan, including Karachi, Lahore, Islamabad and Rawalpindi, tumbled into darkness due to a massive blackout. The country's Power Minister Ayub Khan informed that "a sudden plunge in the frequency in the power transmission system" at Guddu grid in Sindh caused the blackout. While it affected mobile, internet and airport operations, #blackout trended on Twitter in both Pakistan and India with mixed reactions from netizens.
