A limited outage hit the London Stock Exchange’s Refinitiv news and data platform Eikon this week.

The issue stopped users in Asia and EMEA from using data tools or reading news stories, but they could still see headlines and prices.

London Stock Exchange Group (LSEG) completed its $27 billion acquisition of financial market data and infrastructure company Refinitiv in January.

Since then, the service has gone down three times including this week. The previous outages were in April and June.

The cause is not yet known, but appears to be a software issue.

On the physical side, LSEG is in the midst of moving Refinitiv from its Docklands Technical Centre in Poplar to the Cyxtera LHR1 data center in Slough.

The main LSE service, meanwhile, plans to move from its own City of London data center to a Telehouse facility on the Isle of Dogs by 2022.

The stock exchange has suffered a fair number of large and small outages, even before the Refinitiv acquisition.

In 2019, 500 stocks were knocked off the bourse due to a "technical software issue," following an issue in 2018 that delayed trading more than an hour. It also had outages in 2011 and 2009.
