While in rehearsals today, I was a little bored and started running some numbers through my head. Conservative estimates on the number of downloads and the amount of bandwith which Apple would’ve been hit with yesterday. I have no idea how accurate these guesses are, but even so, perhaps when you stop and think about it, you can understand why the servers crashed and failed to deal with the load.
So, without further ado:
- iTunes 7.7 - 100TB
Downloads: 2 million
Size: 50mb - MobileMe - 30TB
Users: 15, 000
Data Transfer: 2gb each, on average - iPhone Software 2.0 - 44TB
Downloads: 200, 000
Size: 220mb
Based on those estimates alone, 174TB of data was moved from Apple’s servers to computers around the world. Woah. That’s a lot of data and strain on the servers themselves. I have even tried to factor in the biggest problem of the day: iPhone activations. I have no idea how many iPhones were sold, or how much data would be exchanged per phone (I’m guessing 500kb). The main issue, though, may have simply been the volume of simultaneous connections.
Oh, and iPod Touch 2.0 software is now live. Have downloaded and am upgrading now.
