How does the script characterize the employees who operate the data centres?

The script characterizes the employees as passionate and dedicated, working hard to keep the data centres running 24/7.

What is the significance of the 'three-million-man-hour' mark mentioned in the script?

The 'three-million-man-hour' mark signifies a significant achievement in safety, indicating that there have been no lost-time incidents over a substantial period of time with a large number of people on site.

How does Google ensure the security of its data centres?

Google ensures data centre security through various layers of security measures, including pre-authorised access lists, biometric iris scanners, and high-level security technologies such as underfloor intrusion detection via laser beams.

What is the typical temperature inside a Google data centre, and why is it set this way?

The typical temperature inside a Google data centre is about 80 degrees Fahrenheit. It is set higher than most because it helps with efficiency.

What is unique about the power distribution system in Google's data centres?

Google's data centres have an overhead power distribution system that brings in high-voltage power from the outside and distributes it across customised bus taps for plug-in extension cords.

How does Google manage the replacement and disposal of failed or outdated drives?

Google has an end-to-end chain-of-custody process for managing drives, which includes checking them out from the server, bringing them to an ultra-secure cage for erasure and crushing if necessary, and ensuring they are 100% clean before disposal.

What is the innovative approach Google uses for cooling its data centres?

Google uses a cooling system where server racks are placed against air-conditioning units, utilizing cool water flowing through copper coils to transfer heat from the air to the water, which is then cooled outside and returned to the data centre.

How does the script describe the pace of innovation at Google's data centres?

The script describes the pace of innovation at Google's data centres as remarkable, with a constant challenge to the status quo and a refusal to accept that innovation in certain areas is over.
