London Stock Exchange hit by glitch after Linux launch

Turquoise big bang suffers networking issues

Article comments

The London Stock Exchange experienced a glitch today on its Turquoise service, 24 hours after the high profile relaunch of the dark pool on open source based systems.

The problem was a networking issue, the LSE told Computerworld UK, and stopped trading between 08.15 and 09.15 today.

The exchange has not given more details on the glitch, but said that Turquoise worked successfully for the rest of the day.

The problem came 24 hours after it switched from the Cinnober platform over to Linux and Unix based systems from supplier MillenniumIT, which it acquired last year. It is not known whether the new systems were the direct source of the issue.

Daniel Garrod, an exchanges analyst at Barclays Capital, told Reuters that “there are often teething problems” with such a large technology migration.

The LSE’s main TradElect trading platform will also switch over to the MillenniumIT systems on 1 November, with a test switch-on this weekend.
