Failover-stay
over:
All requests are sent to server #1. If server #1 fails
all requests are sent to server #2. When Server #1 comes
back on line, All requests continue to be sent to server
#2 until it fails. At that point all requests are sent
back to server #1. |

Failover-switch
back:
All requests are sent to server #1. If server #1 fails
all requests are sent to server #2. When server #1 is
back online all requests are router to server #1. |

Successive
server failover
All requests are sent to server #1. If server #1 fails

| • TZO-HA
is reliable |
| |
| Tzolkin
maintains five redundant DNS server sites located across
North America. These sites are connected through five
different major Intern backbones. This ensures that
your DNS records are protected against any geographic
disruption and against the failure of primary Internet
backbones. The Tzolkin DNS system is proprietary and
is not susceptible to the same attacks that have disrupted
DNS servers running other DNS software. |

| • TZO-HA
is inexpensive |
| |
| TZO-HA
performs many of the same functions of hardware devices
costing 20 to 80 times as much. Because it's a service
TZO-HA does not require the same level of training and
cost of maintenance that a hardware device requires.
A secure web-based interface makes it easy to administer
your TZO-HA account. |
| |
| • TZO-HA
is scalable |
| |
| TZO-HA can support up to 10 different server location.
The location can be geographically dispersed and can
be connected through different backbones. TZO-HA can
also support a wide array of server configurations at
each of these locations. There are also many options
that can increase TZO-HA's functionality. |
| |
| • TZO-HA
is configurable |
| |
| A
secure web-based Control Panel allows complete control
over the TZO-HA service. A version of the Control Panel
runs on any hand held PDA with Internet access and a
web browser supporting SSL for remote access to the
TZO-HA controls. |
