title: Getting suddenly a lot of request from CFNetwork/Darwin
body: <p>I've noticed in the AWS console that our website got a lot of more requests than normally. Especially in the night hours (Europe time).</p>

  <p>Then I've checked the nginx logs and now I know that a lot of devices with different IP addresses request the root of the website, most of them with the user agent <code>swcd (unknown version) CFNetwork/978.0.7 Darwin/18.7.0</code>. Sometimes one of the versions is different.</p>
  
  <p>I have absolutely no idea what is going on so I hope that someone can help.</p>
