The New York Stock Exchange closed today as trading was suspended due to a technical issue.
The exchange used twitter to say it was suspending trading and that it was ‘doing our utmost to produce a swift resolution.’
NYSE stressed that the stopping of trading was not as a result of a ‘cyber breach’.
One tweet said: "The issue we are experiencing is an internal technical issue and is not the result of a cyber breach."
NYSE is owned by Intercontinental Exchange (ICE) which bought the stock exchange in 2012 for $11bn.
NYSE owns and operates two mega data centres, one in Mahwah, New Jersey and one in Basildon, Essex in the UK.
At the time fo the acquisition ICE said it would retain the facilities and continue to operate them.
Also In 2012 NYSE opened up its data centres to outside telcos and service providers.
"Colocation in Mahwah offers participants the most direct route to NYSE market data and trading venues. Customers who colocate in Basildon are afforded the most direct route to ICE and Euronext exchanges housed at that location," the company says.
