TZO-HA, offers a low cost solution to high availability. By deploying TZO-HA services, customers can exceed 5-9's availability for their Internet bound web and mail servers. With Tzolkin's unique technology, TZO-HA has real-time awareness of web server availability. If a primary server/s becomes unavailable, TZO-HA re-writes one or many DNS records to make available the secondary server/s and then propagates that change through Tzolkin's entire domain name server infrastructure "TZO-NET", then through the entire Internet with unprecedented speed. This ensures that only the currently available server/s are properly advertised throughout the Internet.

Proper outbound DNS advertisements are critical for environments which require high availability. Whether it be a single server environment with 2 T1's or multiple world-wide clusters, TZO-HA provides a low cost solution to high availability.
