Don't forget Sharepoint services for large companies too.

Skydrive and Hotmail are some of the services much larger than people realize. Hotmail gives you very large inboxes, like Gmail, and Skydrive backs cloud storage and backup for most Windows devices.

I often wonder what the bandwidth for Windows Update (and MS Download Center for OS patches) is. I would love to see some details on it if it has ever been discussed by MS engineers?

http://technet.microsoft.com/en-us/library/cc627316.aspx gives 500 Gbps for Windows Update in 2008. (2008 announcement: http://blogs.technet.com/b/mscom/archive/2008/04/11/announci...) I can't find recent update.

Thanks!
