The 3DNS product load balances a site across multiple geographic regions. It monitors data centers and server clusters (or individual servers) at each location and takes them out of rotation should an outage at that location occur ensuring that your application has the highest uptime and availability possible.

Most load balancers can push hundreds of Mbps worth of traffic while providing firewall functionality to a site, without any performance hit. Keep in mind that this concept may not fit everyone's needs. Some websites might have a need for a higher level of security like financial related websites.

A brief introduction to load balancing. "Load balancing, in its simplest terms, is a way to divide the work a server has to do between two or more servers. If your business operates its own web site, for example..."
