SINGAPORE/LONDON (Reuters) -London Stock Exchange Group's Refinitiv news and data platform Eikon experienced an outage for several hours on Wednesday before services were restored, the company said, the second such glitch in as many months.
Refinitiv said services began suffering problems at 0119 GMT, hitting banks and other financial firms during the trading day in Asia. Some customers complained on Twitter as the European trading session began but it was unclear how many users were affected.
Refinitiv said it had identified issues with some users not being able to log into some Refinitiv products and services.
"Service has been restored as of 07:51 GMT after Refinitiv support teams took actions to restart the servers," the company said in a note to customers that also apologised for the disruption.
"We are investigating the root cause and ongoing actions we need to take to mitigate recurrence."
Products affected besides Eikon included currency-trading software Refinitiv FXT, as well as Refinitiv Workspace, Refinitiv World-Check One, FXall, MyRefinitiv, Refinitiv Contributions Channel Cloud, Refinitiv Deal Tracker Service and Eikon Auctions, an earlier Refinitiv email said.
Eikon had experienced an hours long outage in April.
LSEG shares were down 0.6% as the broader UK stock market edged higher on Wednesday. The stock exchange group completed its $27 billion takeover of Refinitiv in January. The data provider has more than 40,000 customers and 400,000 end users.
Refinitiv pays Thomson Reuters for news it distributes on Refinitiv terminals. Thomson Reuters holds a minority stake in the LSE.
