Security News > 2020 > October > Tokyo Stock Exchange breaks new record. Sadly, not a good one... its longest ever outage

Tokyo's Stock Exchange went offline for most of Thursday, its longest-ever outage and a very unwelcome one as it is the world's third-largest bourse, when measured by market capitalisation.

The exchange yesterday morning posted news that "a technical glitch occurred to distribution of market data," and the market therefore stopped all trading.

The exchange explained the cause of the outage in a statement that said it experienced "Hardware failure," followed by a failure-to-failover.

While the exchange thought it could replace the hardware and resume trading, doing so would have required a reboot that it felt "Would cause confusion for investors and market participants, which would make it difficult to execute smooth trading."

The exchange continues to do so at every opportunity, with its notification that it expects normal trading today ending with: "We would like to express our sincerest apologies for the inconvenience caused by the system failure of Tokyo Stock Exchange, and we would like to ask for your continued support and cooperation in the operation of the market." .
