The Tokyo Stock Exchange (TSE) has resumed regular operations on Friday after a technical outage that lasted all day Thursday.
TSE is currently planning to replace the hardware and taking steps, including other maintenance, to ensure normal trading from tomorrow onwards, bourse operator Japan Exchange (JPX) said on Thursday evening.
There was no indication that the exchange’s biggest glitch in a decade was caused by hacking or other cybersecurity breaches.
JPX explained that Thursday’s outage was the result of a hardware failure. «The switchover from the failed device to the backup device did not work properly, and as a result, market information could not be distributed, JPX said.
JPX has been on the receiving end of criticism over its crisis management and poor communication to investors regarding the outage.
The matter has also raised questions over Japan’s digital systems and infrastructure, particularly as the country seeks to boost its status as an international financial hub.
