It’s one of the finest resources for every IT technician in tackling the problems, if not for all us to have an insight into how Google’s working internally.
The Opening Grand Story!
The book started with a story of how Google swept through a Wi-Fi password problem, occurred at their New York campus in 2012. It’s a day in September 2012 when the corporate transportation team informed every employee about the change of campus Wi-Fi password, which led thousands of employees to change their passwords immediately, that crashed the Google’s password manager! The flood of employee traffic was so high that, the password manager which was developed 5 years ago for a small set of system admins, has crashed. But that’s not all when the major manager received huge traffic, the load balancer shifted some of the traffic to the other two replicas of the password manager, which eventually failed too. And Google did clear the disturbances was the actual story. The firm needed a Hardware Security Module (HSM) smart cards to restart the service, which were stored in different Google offices across the globe! And when the engineer from the New York office called the Australian office to retrieve a card, it’s, unfortunately, was stored in a safe, and the password to it was forgotten by the engineer who stored! More interestingly, the password for that locked safe was stored in then crashed password manager! Fortunately, one engineer from California remembered the code and retrieved the card, and also the Australian team force drilled the safe to retrieve the card, but none of them worked in the first hour after inserting in the reader, cause they’re inserted upside down! There are other stories as such, defining how Google approached and solved their sudden mistakes by bringing the teams together.
