The 16 August outage, which delayed the market opening by more than an hour and a half, was blamed on a software error at the time.

But UK authorities are now investigating whether it could actually have been caused by a cyber attack aimed at disrupting financial markets.
The incident was the London index’s worst outage for eight years.

The outage immediately triggered government cyber alert systems, and GCHQ is examining whether the software code could have played a role in the incident, according to the Wall Street Journal.

A spokesperson for the London Stock Exchange Group denied the incident was related to cyber security.

“London Stock Exchange takes its commitment to run orderly markets for its members seriously and has thoroughly investigated the root cause of the issue to mitigate against any future incidents,” they added.
At the time of the outage, the London Stock Exchange said it had “experienced a technical software issue” that had “affected trading in certain securities”, including stocks listed on the FTSE 100 and FTSE 250.
