Facebook announces the resignation of two senior officials two days after the biggest technical failure in its history

Facebook founder Mark Zuckerberg announced the resignation of company chief Chris Cox and platform manager Chris Daniels.

Cox joined Facebook in 2005, a year after its founding, while Daniels took office a year ago.

Facebook has not announced clear reasons for their departure.

Cox, who is close to Zuckerberg, started as a software engineer for the company and helped launch several key applications such as News Feed.

Cox has also held several senior management positions in the company: he led the human resources department and also launched the Facebook Workplace platform.

Daniels started as the platform's leader five years after managing the Internet.org initiative, which helps to strengthen online communication around the world.

Daniels will succeed Will Cathcart, who currently runs the mobile phone application for Facebook.

Cox did not say who would succeed him.

• Disable Facebook: the site is facing the biggest technical problem of its history
• What makes Facebook stay "forever"?

The changes took place soon after Zuckerberg announced his intention to turn Facebook into a "privacy platform".

The social networking giant, with its two platforms, Watsab and Engström, has faced the worst disruption in its history this week.

Facebook attributed the crash to a server change.

The company said it has "launched a series of successive releases" of its platforms, including Watsab and Entgram.

The failure, which lasted more than 14 hours, prevented the use of the company's products around the world.

"We are very sorry for the holidays and appreciate everyone's patience," she said.

On Wednesday, Facebook was faced with one of the biggest technical problems in its history and the main service was completely closed to users around the world that day, causing angry reactions around the world.

The last time Facebook was disrupted in 2008, while the number of users did not exceed 150 million users, the number of users is currently 2.3 billion users per month.
