TOKYO -- The connection failure that froze some trading at the Tokyo Stock Exchange earlier this month was triggered by incorrect IP addresses, the bourse is set to report in an official review on Tuesday.
The outage at 7:31 a.m. on Oct. 9 occurred when multiple Internet Protocol addresses -- similar to a telephone number or street address that identifies computers -- were set instead of one, at a brokerage's server. That caused the TSE to be flooded with over 1,000 times the data it normally sends, the report to the Financial Services Agency will say.
