As part of its announcement of the nine million iPhone 5s/5c sales during the opening weekend, Apple also mentioned this morning that 200 million customers have upgraded to iOS 7 since its release last Wednesday. In fact, the mobile operating system has experienced such a rapid adoption that it may have been responsible for a spike of up to 112 percent in last Wednesday’s Internet traffic.

Among traffic hotspots were the US and UK, which have the highest rate of iPhone usage. Just how much traffic are we talking about? Some 2.2 terabytes of data per second spread over 6.3 million downloads per hour, according to one estimate…

According to Akamai’s own real-time monitor of the Internet (via Global Nerdy), Internet traffic was 112 percent above normal at just after 4pm last Wednesday. That’s just three hours after Apple unleashed the iOS 7 upgrade for East Coast iDevice owners.

Just 16 hours after the 1pm Wednesday release, iOS 7 was adopted by nearly a third of iDevice users.

Apple CEO Tim Cook has said the 700 millionth iOS device will roll off the assembly line next month. If about half of iOS devices purchased are still being used, “it puts the number of initial iOS 7 downloads at roughly 100 million, or 6.3 million per hour,” writes Fortune’s Philip Elmer-DeWitt.

The speed at which iDevice owners are upgrading is likely a record and one that should warm the heart of both app developers and Apple.

While the launch of the iPhone 5s and iPhone 5c happened within an environment of doubt over the 5c’s sales and the supply of the 5s, the iOS 7 launch has gone off without a hitch and overall positive media attention.

“This is our best iPhone launch yet―more than nine million new iPhones sold―a new record for first weekend sales,” CEO Tim Cook was quoted in today’s press release. Apple also said that over eleven million unique listeners have tuned in to iTunes Radio since its arrival as part of last Wednesday’s iOS 7 launch.

We can’t tell how this compares to Pandora as the popular Internet radio service doesn’t break down its active listeners by number.

Also, iTunes Radio is currently U.S.-only.

    GTA 5 almost on the same day and sold within one day 800 million dollars and size 18 GB

    • Poet

      Agni’s Philosophy

      • Andre

        Diablo 3

    • Zaidan Umar

      I think your right, that might also be a major reason

    • Rowan09

      Possibly but people usually buy their games instead of downloading it, well in the US we do. Preorders are already made for the games and all people would need to do is pick up the game.

      • احمد بن سليمان العرف

        Most people do not want to stand in long queues to get the game or get it from black market with high prices I guess 50% of people download it from the Internet

      • Rowan09

        GTA came out Tuesday so the spike would be more on Tuesday wouldn’t it?

      • JaeM1llz

        People were able to preload the files before the official release. I know 7 people personally who did this.

      • Rowan09

        That would even give more of a reason why the spike on Wednesday is caused by GTA 5.

    • mehrab

      That’s the money they got not the amount they sold and most people bought cd”s for e.g me

    • TesticularFortitude

      Apple made over $5 billion in 3 days…. And that’s pretending all phones sold were iphone 5c.

    • Canchume

      i think the internet its going to explode in 1 october when gta online release

    As I said on another article, the number of iPhone’s sold during the weekend aren’t that spectacular for some reasons. The first being that it launched in China at the same time as everywhere else for the first time, and the second being that Tim is likely counting both 5s and 5c sales instead of just one.

    • Sebastian Giles

      Good observation! it is kind of odd though, considering how many new features have been introduced in iPhone 5S vs 5…
      I guess the “buying iPhone on launch day” trend is passing

    • Rowan09

      How many iPhones were sold in China? The US is where most iPhones are sold and as I stated on another post, 9+ mil for any company is spectacular. Plus the iPhone 5s sold 5-1 I believe was the number to the 5c and let’s not forget people wanted to buy phones and weren’t able to so the number would even be higher if they had supplies.

    • felixtaf

      Yes brother.. 9 million iPhones in 3 days.. Not spectacular…

  • the best day

  • Mudasir

    I am using IOs 6.1.3 on iphone 4S with gevey sim….I want to update it to IOS 7….Any suggestions…will it effect on performance of my phone…It will work fine or not…..?

    • Allen.B

      is it sprint iphone ?

    • Rowan09

      Is it a GSM if so just do a factory unlock? IOS 7 on a 4S works fine.

    • Quang

      just go online and search for unlock iPhone, such as swiftunlocks.

  • Brian Kieffer

    I highly doubt that there is any correlation between iOS 7 and a 12% increase in Internet traffic.

    • Rowan09

      Why give another explanation?

      • Jo

        GTA 5 was introduced on about the same day

      • Rowan09

        It came out on the 17th which is the Tuesday. IOS 7 came out on the Wednesday at 1PM Est.

      • Jo

        yeah, I said about the same day.

      • Rowan09

        I understand but why wouldn’t you also see some kind of spike on both days? I’m not saying GTA 5 didn’t help but I don’t believe it was the main reason,if even a reason at all.

      Some 2.2 terabytes of data per second spread over 6.3 million “downloads per hour, according to one estimate…”

      If Apple can produce the facts to support this independent estimate then chances are you’re wrong. I know for one thing I remember reading on some blogs and twitter that educational facilities were experiencing huge spikes in traffic that almost brought down their systems due to everyone using the wifi to download iOS 7 OTA…

      • Brian Kieffer

        iOS 7 has been downloaded “only” 200 million times since its release. That’s quite a bit less than 6.3 million per hour. Also, there are many other explanations that are just as plausable: GTA V, typical usage variations, iOS 7, or a combination; however, this article doesn’t mention any of this.

    • Guest

      The fact is many school had to shut down their internet system on that day. My school did experience slow network and had to tell students to stop downloading iOS 7.

  • onebyone_
