From experience, you can't just lock down to that one 
server. You need to
allow port 80 and 443 access to different servers. Each day 
the list of
servers changes because of the Akamai caching that is used. 
I spend some
time configuring locked down systems to be able to talk to 
them. So yes, it
is an unreasonable request.

On the other hand, access to Red Hat Network needs only one 
port and one IP
address. No doubt there's some serious load-balancing going 
on in the

If RedHat had the same "customers times patch frequency times 
average patch size"
product that Microsoft has, they'd be an Akamai customer too...

Indeed they would, but still that would be one IP address and port per
Akamai caching server. Have you ever looked at how many IP addresses you
need access to with Windows Update? 

And please guys, stop cc'ing me. I'm on the list and have been almost since
it started!
