“The London Stock Exchange has put the brakes on its cash
markets migration to a Linux-based system after human error in
“suspicious circumstances” floored the network on its Turquoise
alternative trading venue.“Turquoise, a dark pool or anonymous trading platform, uses the
same system, and this morning took trading offline for two hours
after a “network issue”.“”Human error” was to blame for this morning’s outage on
Turquoise, the LSE told the markets in a statement. But it added
that the problem “may have occurred in suspicious
circumstances”.”
