JPMorgan Chase, Morgan Stanley, Goldman Sachs and Citigroup have asked hundreds of workers to work from home as part of emergency preparedness.

“We are asking some employees to work from home over the next two weeks just so we can test systems and remote access,” said one person familiar with the process, characterizing the step as “typical contingency stuff.”

JPMorgan has undertaken tests at a disaster recovery site in London and two in the United States, in Brooklyn and the state of New Jersey, a source told AFP…

“We have recovery sites and we continually test them,” said a Goldman Sachs spokeswoman. “As you can imagine, we are enhancing our testing in view of the coronavirus.”
