On causes of the outage on April 23, 2012 and undertaken measures A thorough review of circumstances associated with the outage of the Equities market main section on April 23, 2012 was conducted by MICEX-RTS technical team and industry experts.
The analysis pointed to the error in processing a market transaction that triggered fault of the trading system's real time backup solution. Because of that the gateways were unable to verify the validity of distributed data, which in its turn resulted in a halt of orders and trades information being refreshed. The root cause is identified as a simultaneous failure of the software and the hardware that provide redundancy for the trading system.
To eliminate effects of the outage, by the start of trading on the 24th of April, 2012 the faulty hardware unit powering the MICEX-RTS Stock Exchange trading system was replaced. In addition, the set of default outage scenarios has been adjusted. A special test environment was assembled to continue probing and simulating a wider set of outage scenarios.
A working group has been established for comprehensive examination and analysis of the outage causes, development of the rectification measures and recommendations to mitigate the risks of reoccurrence.
