Data Center Knowledge recently published a “Google Data Center FAQ”. As most other web geeks, we here at Pingdom tend to find this kind of information quite fascinating. We have extracted some interesting tidbits, and also used the information to construct a map with all current and under-construction Google data center locations that are known today.

So how many data centers do Google use, and where are they?

Google data center locations

If you include data centers that are under construction, Google has 19 locations in the US where they operate data centers, 12 in Europe, one in Russia, one in South America, and three in Asia. Not all of the locations are dedicated Google data centers, since they sometimes lease space in other companies’ data centers.

We have created a map you can explore over at Wayfaring.

How much does Google spend on data centers?

According to Google’s earnings reports, they spent $1.9 billion on data centers in 2006, and $2.4 billion in 2007.

Google unveiled four new data center projects in 2007. Each has a cost estimate of $600 million, which will include everything from construction to equipment and computers.

Google’s criteria when selecting locations for data centers

• Large volumes of cheap electricity.
• Green energy. Focuses on renewable power sources.
• Proximity to rivers and lakes. They use a large amount of water for cooling purposes.
• Large areas of land. Allows for more privacy and security.
• The distance to other Google data centers (for fast connections between data centers).
• Tax incentives.

What’s up next?

Google has been looking at sites in Asia, such as Taiwan and Malaysia. There are also reports of a possible data center in Lithuania (Eastern Europe). Google is even more secretive about their US locations, but they have bought 466 acres of land in Blythewood, South Carolina.

Google secrecy

Google has made it difficult both to find out where they keep their data centers and how many they have. One big reason for this is that almost all IP addresses that Google uses (and there are a lot of them) are listed to their Mountain View, California address, so just looking at IP addresses (with IP WHOIS or IP-to-location databases) won’t help you figure out where their data centers are or how many they have.

In addition to this, Google usually seeks permits for their data center projects using companies (LLCs) that don’t mention Google at all, for example Lapis LLC in North Carolina and Tetra LLC in Iowa.

Since Google tends to be quite secretive about their data centers in general, the information we have presented here most likely isn’t 100% complete.

Unless you’ve been hiding under a rock lately, you’ll know that last week Apple announced the iPad, its new tablet device. Reactions have been a mixed bag, and a storm of discussion has swept through the blogosphere about various features the iPad should or shouldn’t have had.

One of the main complaints so far has been the iPad’s lack of multitasking. (To be precise, multitasking is a bit of a misnomer here; the iPhone OS has multitasking. What people really mean is only allowing one app at a time to run.)

The tech industry is littered with billionaires. We all enjoy a good income, but some clearly have earned more than others. Much, much more. The question is, how much money do the really big names in tech actually have?

To find out, we went through the Forbes 400, a list of the wealthiest Americans, and filtered out the people who work within the tech field, or more specifically: IT.

So here they are, the 20 richest Americans in tech today.
