Hi All,

I'm attempting to devise a method which will provide continuous operation o=
f certain resources in the event of a disaster at a single facility.

The types of resources that need to be available in the event of a disaster=
 are ecommerce applications and other business critical resources.

Some of the questions I keep running into are:

                Should the additional sites be connected to the primary sit=
e (and/or the Internet directly)?
                What is the best way to handle the routing? Obviously two d=
evices cannot occupy the same IP address at the same time, so how do you pr=
ovide that instant 'cut-over'? I could see using application balancers to d=
o this but then what if the application balancers fail, etc?

Any advice from folks on list or off who have done similar work is greatly =
appreciated.

Thanks,
-Drew
