title: How to avoid web server traffic peak resulting from iOS Newsstand app receiving a remote notification?
body: <p>I'm developing an iOS Newsstand app.</p>
  
  <p>If it is suspended or not running and connected to a WLAN, Newsstand apps can be triggered by a Push remote notification to download the latest issue (in our case around 100MB) in the background.</p>
  
  <p>I'm using Urban Airship for the delivery of the Push broadcast. </p>
  
  <p>I'm now worrying about many many iOS devices hitting the web server for one big download more or less at the same time, because I expect the majority of the devices will receive the notification in a very short timeframe.</p>
  
  <p>Instead of broadcasts to all devices, should I rather send individual notifications to batches of small groups of devices, spreading them out over a longer period of time?</p>
  
  <p>And/or would a CDN like Amazon Cloudfront solve that issue easier/anyway?</p>
