The outage, which began at 1:37:25 pm EDT Friday on MX and 1:39:13 pm EDT on TSX, TSXV, and TSX Alpha, was caused by a hardware failure in a central storage appliance of the trading system. This hardware failure impacted both the primary and the redundant components preventing storage failover procedures from engaging.
Wait. One hardware malfunction takes out both the primary and redundant parts of the system? Looks like the TMX Group should pay for a better setup.
