My.. Our..  Users expect one thing..


It is our job to make that happen. When a electronics manufacturer decides to enable updates for all of their phones world wide.. It breaks things.

When the Internet breaks, it is my fault. Your Apple update sucked because of me.. There is no "it must be apple", as you pointed out earlier. I'm simply saying.. It's a dick move to globally enable updates on a single day and tell ISP's to deal with it.

Why should Apple care if providers have oversubscribed lines or not?  As
far as I know, Akamai delivers most of the data anyway, so it is not
coming all from Apple.  I don't know for sure, but I doubt they have
enough bandwidth themselves to saturate so many links concurrently.  Apple
also does not push the updates, it is pulled to the device when the users
tell the device to retrieve it.  So blame your users, not Apple.  It is
also my understanding that any updates they do push are staged so they all
don't go out the same time.
