Fujitsu chief slashed 50% pay for Tokyo Stock Exchange glitch

In early December 2020, it became known about a 50% reduction in the salary of Fujitsu President Takahito Tokita for a period of four months. This decision was made after a large-scale failure occurred in the computer system of the Tokyo Stock Exchange, which uses the company's equipment, on October 1, 2020. Read more here.

Koichiro Miyahara sacking after biggest IT outage on the exchange in history

At the end of November 2020, it became known that the President of the Tokyo Exchange (TSE) Koichiro Miyahara was resigning. By his decision, Miyahara intends to demonstrate responsibility for the technical failure that provoked the shutdown of trading on the stock exchange for the whole day on October 1, 2020.

Shutdown due to failure of IT equipment used since 1999

In early October 2020, the Tokyo Stock Exchange experienced the most serious disruption in its history. On Thursday, October 1, trading was terminated for the entire day due to a malfunction of a computer system developed by the exchange in collaboration with Fujitsu. Although no definitive explanation has yet been provided, it is assumed that the shutdown of the system was not related to the hacker attack.

The exchange said the outage was due to problems in the Arrowhead system and asked Fujitsu to investigate the equipment involved. But at a hastily organized press conference to explain the events of the day, Tokyo Stock Exchange officials said that it was not the equipment suppliers who were to blame for the problem, but the operators themselves. The exchange is not considering damages from Fujitsu.

Tokyo Exchange Completely Shut Down Due to IT Hardware Failure Used Since 1999

All responsibility lies with us, "said Koichiro Miyahara, CEO of the exchange. - Fujitsu is simply an equipment supplier.

Fujitsu spokesman Takeo Tanaka said the company is ready to work with the exchange to prevent further problems.

We apologise for any inconvenience caused to stakeholders by the failure of our equipment, "he said.

The Arrowhead system, in use since 1999, withstood a powerful earthquake and tsunami that struck northeastern Japan on March 11, 2011. Buildings in Tokyo felt a lot of shaking, but trading on the stock exchange did not break. However, a computer glitch in 2012 stopped trading in securities, and due to a system error in the same year, derivatives trading ceased for almost an hour. In 2015, Fujitsu and the Tokyo Exchange began updating computer systems to ensure a reliable uninterrupted operation of the exchange, which seriously affects global markets. Among the changes implemented then was a new modular approach that allows you to disconnect faulty servers and redirect their tasks without losing data.^[1]
