London Computer Glitch

If you think it's frustrating when your computer crashes, just be glad you're not running the London Stock Exchange. Trading in Europe's biggest stock market was suspended nearly all day after a system failure. When trading eventually resumed, British stocks ended the day up almost 4%. But London wasn't the only market affected by the outage. Trading in South Africa was also suspended because the Johannesburg Stock Exchange also uses London's technology platform to handle its trade processing.
