That's just the basic DNS functions, no real geo traffic redirection/ fail over / dynamic updates logic built in.

<div class="content wysiwyg-content">
I have 2 sites: site.com and us.site.com<br />
site.com (1.1.1.1) is hosted in Asia and us.site.com (2.2.2.2) is hosted in USA<br />
<br />
The majority of &nbsp;the visitors located in USA go to us.site.com<br />
A few visitors located in USA &nbsp;and using site.com are directed &nbsp;to us.site.com with code using GeoIP location.<br />
The problem is when the site.com fails those few users get an error.<br />
<br />
I may use 2 A records for site.com (1.1.1.1 and 2.2.2.2) to overcome this problem but in this case lots of visitors (may be the majority) located in Asia will be redirected to 2.2.2.2 depending on the browser behaviour.<br />
<br />
I can redirect the Asian visitors to 1.1.1.1 with code but this solution is very inefficient.<br />
<br />
How can I solve this problem?

DNS and IP location problem

Cloud computing, also known as on-demand computing, is a kind of Internet-based computing where shared resources and information are provided to computers and other devices. It is a model for enabling ubiquitous, on-demand access to a shared pool of configurable computing resources. Cloud computing and storage solutions provide users and enterprises with various capabilities to store and process their data in third-party data centers, relying on sharing of resources to achieve coherence and economies of scale.

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

PHP is a widely-used server-side scripting language especially suited for web development, powering tens of millions of sites from Facebook to personal WordPress blogs. PHP is often paired with the MySQL relational database, but includes support for most other mainstream databases. By utilizing different Server APIs, PHP can work on many different web servers as a server-side scripting language.
