Why no emphasis on Business continuity within the I.T. Management infrastructure?

Why is it that in this day and age of buzzwords and phrases like "Business Continuity" there little or no emphasis made on the need for the management tools required by the IT department to be fault tolerent.

There seems to be a big deal made of web farms and clustered sql servers etc. That's fine for the business, but, what happens when the Infrastructure management tools are unavailable?

Picture this: Your only link to the internet is down, your company is losing money because your web shop is unavailable. Your users are screaming, but you can't do any investigation or corrective action because your Management system is offline due to an unforseen server hardware fault! Who is going to get fired for this?

I have been speaking with quite a few prospects recently where they have a look of horror on their face when you ask this question!

So, how many Infrastructure Management tools have been designed with Business Continuity in mind? I know mine does, but, does yours? If it does, please, let me know, what is it called?
