On Thursday 1st of October 2020 the world 3rd largest Stock Exchange has halted its trades due to a malfunction of one piece of hardware. The outage has resulted in entire day of trades being frozen out in the $6 trilion market cap exchange.

As of 8 a.m. traders have reported glitches around the data points being provided in their trading terminals in regards to indicative prices, with some reporting lack of data.
A minute later the Stock Exchange has informed sys admins at security firms that there is likely an ongoing issue.
By 8:36 a.m. the trading was officialy halted after confirmation from the Stock Exchange following a press release published in Japanese.
One of the criticisms is of the exchange's communication, with a confusingly translated English version of the press release coming out hour later after the Japanese press release.
The root cause of the outage has been identified to be related to the primary shared disk device memory breakdown.
A further issue arised during the automatic failover from the primary shared disk to a secondary with a lack of explanation from the exchange so far in regards to the root cause.
Later in the day an announcement was put forward that the trading would restart on Friday
