title: What's the best way to catch Firebase ajax errors?
body: <p>I tried posting this in the Google Group as a statement and not a question but it didn't go through. :\</p>
  
  <p>Firebase had some downtime the other night, and a call to <code>FirebaseAuthClient</code>'s <code>createUser</code> function was not going through, but its callback was not being called with an error.  In Chrome's dev tools, I could see that the underlying GET request was failing.</p>
  
  <p>Can Firebase be updated so that all functions that rely on an ajax call return an error if the ajax call fails?</p>
