TZO-HA’s DNS Failover is the foundation for service based high availability and has the unique capability of maintaining extraordinarily low cache times. With embedded server monitoring,this allows for near real time traffic redirection. When TZO-HA detects a failure it automatically updates the DNS record for your domain so that the server requests are sent to the IP address of your alternate server or server cluster.

• Geographic Load Balancing
..
Geographic load balancing deployed entirely as a service has revolutionized the global load balancing industry. With no hardware to deploy and no software to configure, TZO-GEO offers a complete paradigm shift for true global traffic management.
With "N" number of participating server/s or IP addresses, as an inbound DNS query comes in to the TZO DNS infrastructure, we lookup the Source IP address of the DNS query. We then match that source IP to a database of IP addresses and geographic longitude and latitude definitions. When a geographic location is found for the source DNS query IP address, we then calculate which of the participating servers is closest in proximity to the originating DNS query. This all happens in milliseconds and poses no detectable latency to the standard DNS query. Read more….
• Server Monitoring
..
TZO-HA monitors your server(s), dynamically from multiple monitor points across the world. Every few seconds, TZO-HA agents monitor your server within the protocol you select. Not only can it check the availability of your server and your server software functionality, but also it can check the validity of the content being served. All this at a fraction of typical monitoring software prices. Including Multi-Point Monitoring. Read More …. >SeeFlash Description
