Google two years back in December 2009 launched Google Public DNS in order to make the web faster – yesterday Google reported that its Google Public DNS service is the largest in the world with handling an average of more than 70 billion requests a day.
The search giant reports that about 70 percent of its traffic comes from outside the United States – maintaining a stronger presence in Americas and Europe – even in addition to this adding entirely new access points to different parts of the world including Australia, India, Japan and Nigeria.
Here’s what the company had to say about the Public DNS project:
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.
Shortly after launch, we made a technical proposal for how public DNS services can work better with some kinds of important web hosts (known as content distribution networks, or CDNs) that have servers all of the world. We came up with a way to pass information to CDNs so they can send users to nearby servers. Our proposal, now called “edns-client-subnet,” continues to be discussed by members of the Internet Engineering Task Force. While we work with the IETF, other companies have started experimenting with implementing this proposal.
Google hopes to make the web experience faster for its users across the world -Google Public DNS’s goal is simple: making the web—really, the whole Internet!—faster for our users.
