The Apple effect on ISP traffic


On October 12th, Apple released the newest version of iOS for it’s handheld devices, iOS version 5. This update is available for virtually all of their i-devices.

A customer asked, “I’d be interested in hearing if Sonic sees a significant traffic spike today due to “massive Apple updates day”, so we decided to pull some stats.

The answer is that yes, there is a substantial increase in traffic starting the day the update was released. We host the Apple update content locally on Akamai CDN servers in our datacenter, so this doesn’t affect our network edge, but you can see the bump in traffic from the CDN cluster itself here.
