Connectivity problems forced the Tokyo Commodity Exchange (Tocom) to suspend all trading for over three hours today, just a month after a new technology platform developed by Nasdaq OMX went live.
Tocom says connectivity problems arose at its shared network gateway for some members at around 10.30am local time, leading to the suspension of the session for all products at 11.35am.
The exchange was forced to switch off its router while it tried to identify the cause of the problem. Although the cause was not found, system connectivity was restored by around 2.00pm with the day session resuming at 3.00pm for half an hour.
The night session - an initiative only introduced when the new platform went live - will resume as normal at 5.00pm.
Tocom only went live with its "Next Generation System" on 7 May following around two months of mock trading sessions. Nasdaq OMX provided the technology for the trading and clearing platform, with NTT Data as prime contractor and system integrator.
