BlackBerry on Monday announced that it will cease operations in Pakistan at the end of the year. The move is the result of a shutdown order from the Pakistan Telecommunication Authority, which in July notified the company that its BlackBerry Enterprise Service servers would no longer be allowed to operate in the country beginning in December for what it said were security concerns. The government wanted to monitor all BES traffic, including every BES BBM message and BBS email, prompting the decision to leave the country, the company said.
