I've found that CyberDuck works great internally in our environment but has issues when attempting to reach external sites. The issue appears to be of our authenticating proxy. CyberDuck appears to have known issues operating with a setup like ours, especially for HTTPS traffic to a site like Rackspace.
I'm continuing to try and get the developers of CyberDuck to address the issue, but thus far we're stuck. Does anyone know of an alternative to CyberDuck that offers a similar feature set?
