Now it's given us something even cooler - and more rare: a look at itself.
The search giant has posted a huge collection of images, tours, videos and information about its data centres and other infrastructure that keeps the web functioning.
It's a fascinating tour, and includes many eerie glimpses of its inner workings. (Which are, apparently, all lit up in neon like the original Tron movie).
"When you're on a Google website (like right now), you're accessing one of the most powerful server networks in the known Universe," Google said.
"But what does that actually look like? Here's your chance to see inside what we're calling the physical Internet."
For one of its data centres Google is letting users literally walk around inside - through Street View.
"You can now explore our Lenoir, NC data center at your own pace in Street View. Walk in the front door, head up the stairs, turn right at the ping-pong table and head down the hall to the data center floor. Or take a stroll around the exterior of the facility to see our energy-efficient cooling infrastructure. You can also watch a video tour to learn more about what you're viewing in Street View and see some of our equipment in action."
