Re: iOS 7 update traffic

[Fred Reimer <freimer () freimer org>]

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.
