Dive Brief:

• Facebook now has a new CIO, Atish Banerjea, a global technology executive who previously served as the EVP and CIO for NBCUniversal Media. 

• Banerjea joined the social network in October, according to his LinkedIn. He replaced Tim Campos, who announced in April he was leaving to start a new company and had planned to stay with Facebook through the year's end. 

• At Facebook, Banerjea is responsible for overseeing the global information technology function. According to his LinkedIn profile, his team is "responsible for building and running systems that will help scale Facebook globally enabling the company to continue making the world more open and connected."

Dive Insight:

In May, Facebook said it was looking to replace Campos with someone with strong technical leadership and the ability to R&D with new enterprise systems. 

As CIO, Banerjea will have to be prepared to support a global workforce that has to leverage technology for its more than one billion users. A large part of that is finding ways to ensure connectivity and make sure the backend stays up and running. 

Facebook is already at the forefront of using new technologies and innovative testing, particularly when it comes to their ability to react to disasters. The social network regularly conducts live stress tests on its operational networks to make sure they can put their data centers back together quickly and efficiently in the event of some sort of disaster.
