Deutsche Börse's Xetra this morning became the latest trading platform to succumb to technical problems after it suffered a two-hour outage due to "hardware failure".

The Xetra platform began operating at 08:00am central European time but at 08:33 the exchange noted on its message board that it was suffering from a "failure" in the Xetra trading system. Just before 09:00 the exchange announced it would delay the opening of the market, which resumed at 10:15 with a five minute auction.
