Microsoft blocks IM service to countries deemed hostile to the U.S.

Microsoft has announced that users in five countries will be blocked from using Windows Live Messenger. The popular instant messaging service is now off limits to people living in Syria, North Korea, Iran, Sudan and Cuba. All of those countries have U.S sanctions against them and are continued to be hostile or threatening to our national interests.
