Google Public DNS Service Now Largest In World; Handles 70 Billion Requests A Day

When Google launched its Public DNS service back in December 2009, it aimed to be an alternative to the other Domain Name System (DNS) resolution services. Now fast forward two years later and it is now the largest DNS  service in the world handling an average of 70 billion requests a day.

 In a new blog post, 70 per cent of Google’s Public DNS traffic comes from outside the U.S, establishing a strong presence in North America, South America and Europe, while increasing their presence in Asia. Google also had added new access points to areas that didn’t originally have access to their Public DNS service including Australia, India, Japan and Nigeria.

Explaining how DNS works, software engineer for Google Public DNS Jeremy K. Chen said:

“DNS acts like the phone book of the Internet. If you had to look up hundreds or thousands of phone numbers every day, you’d want a directory that was fast, secure and correct. That’s what Google Public DNS provides for tens of millions of people.”

For those using Google Public DNS, the company claim that the service results in a speedier browsing experience, improved security and they only temporary collect IP address to make the service faster before erasing any IP information after 24 hours.

So with 70 billion requests a day (we’re not even going to attempt to calculate how many that is in a year), you’d imagine that Google are relatively happy with how well the service is going.
