Here are some comparisons:
Facebook users upload 300M photos per day. Assume an average file size of 100kB. Of course, they do other things as well.
Netflix has 7M customers who on average stream 5 TV shows and 4 movies per week. In other words, they stream the equivalent of an iOS upgrade (including iTunes upgrade) each day.
Depending on how many *millions* of Apple customers were upgrading yesterday, it is possible the traffic load was close to the same scale as what FB, Netflix and others face daily.
But let's say it's much more. There are companies that can handle it.
For example - AWS: They store 500B+ "objects" and handle close to 400k requests per second. What does this mean? Object size varies, of course. But clearly they handle bigger traffic loads daily than what Apple had to handle yesterday. So yes, someone in the world could have dealt with this.
Having said that, Apple is an Amazon customer. So it's a question of how much they depended on AWS, Microsoft and their own data center.
