Google DNS handles 70 billion requests a day

Google announced the launch of their Public DNS, way back in December 2009 to help make the web faster for everyone. Back then, it was more of an experiment to see if it actually did help. Today, it’s no longer an experimental service. Google is the largest public DNS service in the world, handling an average of more than 70 billion requests a day, which in itself is a whopping statistic. This has been stated by the official Google blog.


For those not in the know, the DNS basically acts like the phonebook of the Internet. If you had to look up hundreds or thousands of phone numbers every day, then you’d want a directory that was fast, secure and correct. That’s what Google Public DNS provides for tens of millions of people. The DNS helps in filtering, searching and looking up by tens and thousands in the digital world. 

Google used a feature called Trends for the numbers

Going strong!



Google Public DNS has become particularly popular for users internationally, as well. Today, about 70 percent of its traffic comes from outside the U.S. Google has maintained an extremely strong presence in North America, South America and Europe, and along with that, it has also beefed up its presence in Asia. Google has also added entirely new access points to parts of the world which previously didn't have Google Public DNS servers, including Australia, India, Japan and Nigeria.


Shortly after launch, Google 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. The company came up with a way to pass information to CDNs, so they can send users to nearby servers. This proposal is now called “edns-client-subnet” and it is quite popular amongst the members of the Internet Engineering Task Force. Other companies have started experimenting with implementing this proposal as well. 


Anyway, that is one hell of a statistic. It is fair to say that Google has effectively divided the web into two halves – one that works completely dependent on Google and its services and the other that doesn’t.
