Same here, was just about to start a thread myself.
Manifest download error for http://patch.savecoh.com/manifest.xml
The remote server returned an error: (503) Server Unavailable.
I'm getting the same type of issue on the Torchbearer server, although my error code changes with every attempt.
According to this thread, it's happening on multiple servers, not just Torchbearer.
