title: Cocoapods timeout issue
body: <p>I've been using cocoapods for a while now and never had any issues but since yesterday I've been getting timeouts from GitHub whey trying to execute <code>pod install</code>.</p>
  
  <p>Here's my podfile:</p>
  
  <pre><code>source 'https://github.com/CocoaPods/Specs.git'
  platform :ios, '7.0'
  use_frameworks!
  
  pod 'iCarousel'
  pod 'SwipeView'
  pod 'AFNetworking'
  pod 'ActionSheetPicker-3.0'
  pod 'WYPopoverController'
  pod 'MarqueeLabel'
  pod 'MZFormSheetController'
  pod 'TPKeyboardAvoiding'
  pod 'SVPullToRefresh'
  pod 'ReflectionView'
  pod 'SCLAlertView-Objective-C'
  pod 'iOS-Slide-Menu'
  pod 'MONActivityIndicatorView'
  pod 'HexColors'
  pod 'ICViewPager'
  pod 'SlackTextViewController'
  pod 'STTweetLabel'
  </code></pre>
  
  <p>When I try to run <code>pod install</code> I get this message:</p>
  
  <pre><code>Analyzing dependencies
  Downloading dependencies
  Installing AFNetworking (2.5.0)
  
  [!] Error installing AFNetworking
  [!] /usr/bin/git clone https://github.com/AFNetworking/AFNetworking.git /Users/georgichristov/Documents/Workspace/Examples/IOS/DigiGraff-IOS/Pods/AFNetworking --single-branch --depth 1 --branch 2.5.0

  </code></pre>
  
  <p>Sometimes it manages to install more than one pod but fails to install all of them, thus making my project basically unusable. Any idea on this?</p>
