Compare those costs to the cost of the service outage. Your business
will dictate how long of an outage it can sustain. Don't forget to
include the expense to restore service such as possibly the cost for
a technician and associated costs as travel time and expenses.

Do any of you have redundant highspeed internet connections for
(versus those for datacenters)? If so, what kind of setup do you have?
Here's the setups I'm considering...
1. Have a second cable modem/dsl modem active, but not hooked into the
network. In the event of a failure, move the connection for perimeter
devices over to the standby connection and reconfigure the
to use a different IP.
2. Have a second set of perimeter devices (firewalls) programmed to
IP's on the second connection, as a hot standby.
My problem with the first option is the time it would take to
firewalls and IDS' to use the other ISP's connection. The problem I
with the second is the expense of firewalls and IDS' just sitting
Any input is greatly appreciated!
