title: How to deal with MKReverseGeocoder / PBHTTPStatusCode=503 errors in iOS 4.3?
body: <p>Since iOS 4.3 (GM Seed 10M2518) I'm getting crashes when using <code>MKReverseGeocoder</code>. <code>reverseGeocoder:didFailWithError:</code> gets called with an error like this quite often:</p>
  
  <p><code>Error Domain=NSURLErrorDomain Code=-1011 "The operation couldn’t be completed. (NSURLErrorDomain error -1011.)" UserInfo=0x339900 {PBHTTPStatusCode=503}</code></p>
  
  <p>The app tends to crash at these moments.
  This hasn't been the case in previous versions of iOS.</p>
  
  <p>Any ideas what happened?</p>
