Apple claims 200 million[1] IOS devices upgrade to version 7 in the past 
week.  A typical download was on the order of 800MB.

At the same time, Apple released some other updates, like OSX 10.8.5[2]
(275MB) and XCode 5.0[3] (2GB).  They also made the iWork and iLife
applications (Pages, Numbers, Keynote iMovie, and iPhoto) free to 
download[4] for all new IOS purchasers.

Oh, and they sold 9 million iPhone 5s/c devices[1], most of which needed
an update to IOS 7.0.1[5] which was a 1.2GB download.

With all of that going on the grumbling on NANOG has pretty much been
limited to "yeah, we saw a spike", and a few providers of alternative
technologies (like Satellite) grousing a bit.

I'm not saying the industry can't do better, but I'm finding it hard to
describe what happened as anything besides a success for CDN's and most
consumer facing ISP's.  I only hope the various CDN's and ISP's study
what happened so they can be prepared for the next event, which will
no doubt be bigger.  We're all in an "up and to the right" industry.
