History question

On September 8, the Moscow Exchange suspended trading on the derivatives, foreign exchange and stock markets for more than two hours. “One of the network switches created an abnormal load on the network, which caused instability in the operation of not only the main, but also the backup network components,” the exchange explained the reason. On September 1, there was no trading on the stock market for almost an hour. The emergency situation occurred due to unstable operation of the “hardware of the main server of the stock market trading and clearing system.” On August 12, trading on the derivatives market was suspended for half an hour due to incorrect operation of telecommunications equipment, which “led to problems with clients receiving market data.” On June 15, during the evening session on the derivatives market, trading not only began an hour late, but subsequently did not take place for more than two hours. The reasons for the delay are “the lack of flow of market information and the impossibility of resuming it without rebooting the trading system.” On March 5, the exchange suspended trading on the foreign exchange market and the precious metals market for more than an hour. The failure was caused by “incorrect processing by access servers of the foreign exchange market trading system of a risk balancing service transaction between the derivatives and foreign exchange markets.” On January 12, trading on the derivatives market was suspended for almost an hour due to “de-synchronization between two transaction processing processes.”
