The arrival of iOS 5 crashed the entire network yesterday.
Hey iPhone users, if you had trouble installing this great iOS update yesterday, don't worry, almost everyone did. The most significant error we saw was error 3200; Apple's servers couldn't handle so many updates at once. It was incredible.
But that's not all; the iPhone software update caused a spike in the download graph, which you can see in the image. At 19:00 PM, internet traffic almost doubled, all thanks to Apple and its iPhone; everyone was trying to download a huge file at the same time.

Those who couldn't install it yesterday, try again today; there shouldn't be any problems. 😀
