A huge project is now taking place globally - the Project Titan by Verisign.

Project Titan is to expand the critical infrastructure both in scale and location globally and investment in engineering, monitoring and new proprietary security systems and processes to manage Internet traffic.

By 2010 VeriSign will increase its daily DNS query capacity tenfold from 400 billion queries a day currently to 4 trillion queries a day. It will also scale its proprietary systems to increase its bandwidth capacity ten times from more than 20 gigabits per second (Gbps) to greater than 200 Gbps. By distributing its infrastructure, the .com and .net systems will have greater redundancy and reduced latency, which will improve the experience for users by reducing bottlenecks and increasing speed. The state-of-the-art engineering enhancements to the system will create increased capability to track and correlate security and network related events on a global basis.
