the problem appears to be socket.io javascript loading from cdn.socket.io here is a screenshot showing it tok 32.49 seconds to load renderosity.com you see in the list it took 29.68 seconds to load socket.io -11.3.4.js

so I did a traceroute to cdn.socket.io here:

and taking forever to connect cloudfront which is an amazon service. So the problem appears to be still with amazon. I don't know if it is socket io not being able to connect or the node not respoding. Anyway that is as far as I got. After your connected everything seems to load ok.
