The day Google launched its social network Google+, Facebook CEO Mark Zuckerberg called an emergency meeting and declared the company on ‘lockdown’.

According to an excerpt from a new book, written by former Facebook manager Antonio Garcia Martinez says, “We received an e-mail at 1:45 P.M. the day Google Plus launched, instructing us to gather around the Aquarium, the glass-walled cube that was Zuck’s throne room. Actually, it technically instructed us to gather around the Lockdown sign. This was a neon sign bolted to the upper reaches of the Aquarium, above the cube of glass, almost like the NO VACANCY sign on a highway motel. By the time the company had gathered itself around, that sign was illuminated, tipping us off to what was coming.”

However, Google+ never came remotely close to the popularity of Facebook. The CEO has also been addressed as aloof, geek-speak and borderline psychopathic.

The full book, “Chaos Monkeys: Obscene Fortune and Random Failure in Silicon Valley,” is expected to hit the bookshelves later this year.
