  <p>I've checked their <a href="https://status.github.com/" rel="noreferrer">status page</a> and "All systems operational" so I'm thinking it must be something with my configuration. My <code>.gitconfig</code> file just have my name and email:</p>
  
  <pre><code>[user]
      name = Bradley Wogsland
      email = &lt;omitted&gt;
  </code></pre>
  
  <p>(I've omitted my real email here but in the actual file it's there).</p>
