iOS 7 used 20% of one unnamed North American ISP’s web traffic on release day, September 18th, 2013. The unknown ISP announced this information via Sandvine’s Global Internet Phenomena Report for the second half of 2013. The report said that Apple’s iOS 7 update immediately took 20% of network traffic and continued to stay above 15% of total traffic into the peak evening hours of September 18th.
Via the report:
Most interesting is the fact that the launch noticeably increased the total volume of traffic during peak hours. This presents a unique challenge for operators, since they must engineer their networks for peak demand, and Apple product launches and software updates are infrequent in nature,
It’s not surprising to see the iOS 7 update put such a heavy load on ISPs as the updates themselves were large, with the iPad update clocking in at 1.4GB when installed through iTunes. Over-the-air updates were a little bit smaller, however, with the iPad 2 update clocking in at 900MB.
The report also shows that video streaming is still dominating web traffic overall with YouTube, Netflix, Amazon Instant Video, and Hulu accounting for 18.69%, 31.62%, 1.61% and 1.29% of downstream internet traffic respectively.
