Nyse Euronext says trading systems were unaffected by an electrical fire at its New Jersey data centre on Sunday.
The exchange operator says the fire broke out in a room housing connections to other data centre facilities for 58 clients, temporarily affecting communications.
However, in a notice sent last night, Nyse said no one was injured in the blaze and that "trading systems were not affected, and will operate on a normal schedule tomorrow, Monday, Oct. 10" .
