iOS 7 update doubles UK and German net traffic and may have reached 100m
Apple iPhone and iPad users drove data demands on some ISPs around the world to double from their normal levels on Wednesday evening as they tried to download iOS 7, the latest version of the Californian company’s operating system.
By Thursday morning an estimated 130m people had updated their devices – based on data from Mixpanel, an analytics company which tracks the OS being used on apps and web pages.
It found that by mid-afternoon on Thursday in the UK, 10 hours after iOS 7 was released, 33% of iOS devices it monitored were running iOS 7 – compared to 2.9% before its release, which would have been use by developers with pre-release versions – and that the figure was growing by about 1% per hour. Separate calculations by Benedict Evans of Enders Analysis suggest that there are 415m “live” iOS devices, excluding the Apple TV. Extended across all devices, that would imply 130m iOS 7 users in less than 12 hours.
But Cook’s claim – made as he showed off Apple’s new iPhones last week – that iOS 7 would soon become “the world’s most popular operating system” may have to wait for validation: more recent versions of Android are used on around three times as many devices.
Evans reckons there are 785m working Android devices which have been activated by Google. Google’s own data on its OS fragmentation suggests that 36.6% of active Android devices are using Android version 4.1.x of “Jelly Bean”, and 8.5% using version 4.2.x. That would translate to 287m users of Android 4.1.x, and 66.7m using Android 4.2.x – a total of 353.7m.
Even so, demand for the free download – which averaged 750MB but peaked in size at 1.4GB for some iPad models – meant heavy loads for ISPs woridwide. In the UK a graph from the London Network Access Point (LONAP), which provides services for ISPs across Britain showed an abrupt spike at 6pm as the download become available. Demand peaked at about 9.30pm as Apple’s servers, which had initially struggled, began running more smoothly.
BT Retail told the Guardian that traffic levels were at the highest ever seen: “within 20 minutes of the launch traffic grew over 200 gigabits per second,” said a spokesperson.
In Germany, where the Berlin Internet Exchange saw an increase of over 10 gigabits per second as the download become available at 7pm local time.
But the traffic blitz was not limited to the UK and Germany. Global Nerdy reported on Wednesday evening that internet traffic in total was 12% above normal as the download became available, using data from Akamai.
In October 2011, the release of iOS 5 caused a similar jump in data traffic with throughput jumping by 200 gigabits per second. However iOS 6 was less well received because of fears over its Apple-generated Maps app, which seems to have put some people off upgrading.
