“The London Stock Exchange suffered its worst systems failure in eight years on Monday, forcing the world’s third largest share market to suspend trading for about seven hours and infuriating its users. (…) Monday’s trading suspension was the longest suffered by the exchange since April 5, 2000, when problems with an older trading system led to an eight-hour suspension.”

The Exchange uses LSE TradElect, a Microsoft .Net application that runs on Windows and SQL Server. What surprises me is that they did not elect to go into DR. From an earlier press release, the TradElect “platform has been designed to the highest levels of resilience with comprehensive back up, which includes dual processing at two sites and recovery from component failure within a second.”
