"A Linux-based trading platform at the London Stock Exchange was
knocked offline for two hours on Tuesday due to human error, in
what may have been suspicious circumstances, the stock exchange
said on Tuesday.
"The trading platform — named Turquoise — has been
running on a new Linux-based system for the past two weeks. It was
rendered inaccessible to market members for two hours on Tuesday,
between 8:23am and 10:30am, the London Stock Exchange Group (LSEG)
said in a statement.
"Turquoise is a pan-European trading platform based in London.
It has a 'dark pool' trading component that allows members to
"place large orders for trades which are not made known to the
market until after the trade has been executed", a spokesman for
the London Stock Exchange told ZDNet UK on Wednesday."
