Hi! I know absolute nothing about the Chinese firewall, but using this tool, everything looks OK: http://www.websitepulse.com/tests/6702b3e05295d559.html
If you'd like, email us here, and we can see if we can't find out what's going on.

Thanks!

(FWIW, I even tried the "official" (webdav) sync URL, and that appears to be working as well.)
