iOS 7 update traffic

In my experience just having a Akamai cache wasn't enough to handle this.
Our local cache was doing 15 out of 20gbps usage and seemed pegged at
that. One of our customers had a local Akamai cache on there end crash and
we were mostly filling a 10gbps pipe to a datacenter with limelight cdn's
at it. This was just the CDN spike and not the one's over our peering and
commodity traffic. 

Yes apple might not of forced people to upgrade exactly at the time they
released but they can at least do an enforced role out like google does(on
much smaller updates of course).

Our core handled it all with not much more then amazement from our staff
but a majority of customers pipes were pegged at whatever bandwidth they
were paying for(I'm talking between 200mbps-5gbps with a few as big as
10gbps customer connections)
