IOS7 was released (Yesterday?). Due to the large number of IOS devices out in the world. Some network operators experienced large spikes in traffic as each device was updated (Downloading the update). You see the same thing happen when new software is released from people like Microsoft. Or, If you're a gamer. When a new game is released on a digitally delivered platform like Steam or EA's Origin.

We also saw a huge spike in traffic. Still pretty high today as well. We saw a ~60% above average hit yesterday, And we're at ~20-30% above average today as well. Being an android user, It didn't dawn on me until some of the IOS users in the office started jumping up and down about IOS7 Nick Olsen Network Operations (855) FLSPEED x106

We also noticed an interesting spike (+ ~40%), mostly in akamai. The same happened on previous iOS too.

I see it here, too. At its peak, our traffic levels were roughly double what we would see on a normal weekday.
