To be honest, I don't see this as a problem at all. Use it as an excuse to upgrade your pipes, talk Akamai or CDN of choice into putting a cache on your network, or implement your own caching solution. As operators of the Internet we should be looking for ways to enable things like this, not be up in arms at Apple for releasing an update to their phone OS or making it available in a way that's inconvenient to our oversubscription policies.

As a side note, how are some of you not aware of this? This has happened with every single Apple OS update since the iPhone was released in 2007. This isn't a new phenomenon. I realize some of you are too cool for Apple, but paying attention to traffic trends and keeping abreast of how new software releases might affect your utilization is part of properly running a network.

I bet this would be a larger deal to Nanog people if your Internet stopped working as the result of 100% Linux adoption. That is very close to what this is.. Tens of millions of people trying to update their 13 ios devices at the same time. Who owns a single ios device? A household could do 5-10gb worth of updates in a single day..
