The issue is really not Akamai or Digital Island or any other service 
someone might buy.  The end user is completely unaware of the machinations 
behind the scene, they are just going to type "" into 
their browser.

If "" is a Bad Domain and ISPs refuse to resolve anything in 
that domain, then nothing else can happen.  The first step is the end 
user's machine going to the ISP's name server asking for the IP address of 
"".  It does not matter if that hostname is CNAME'd to 
another company / host / whatever, the resolution will stop immediately and 
the user will be unable to see the web page.

Or they can just use a publicly available web proxy, in which case it will 
not matter if the domain is Akamaized or not. =)
