Employees wade through the Chennai office of Infosys.
Chennai's Infotech hub was shut down this morning following heavy flooding in the area. Most companies are struggling to get the stranded employees home safely.
The city is a major IT outsourcing hub for companies including Infosys, Tata Consultancy Services and Cognizant Technology Solutions.
In a statement, IT major Infosys said they were closing the campuses as a "precautionary measure".
"The flooding at the Mahindra City campus has been caused by some neighboring lakes overflowing following the incessant rain," the statement read. "At Infosys, the safety of our employees is priority and we have made necessary transport arrangements to get employees home safely."
Unconfirmed reports said the water has reached the first floor of the Accenture office.
Cognizant, which has its largest office in Chennai with 60,000 people across 11 facilities in the city, said some of its employees have stayed back in office to support critical services while some have travelled to other cities to support operations.
