FWIW, it seems to have been caused by one particular thread - I was able to work around it by doing a post-sample request (using Forte Agent) and only one post persistently failed. Unfortunately, there's no data available from the Bridge.
It's very similar to an error I get from the Community Bridge over in Answers occasionally, where the post has been deleted, and it seems that the permissions on it are screwed so that the post is seen by the Bridge, but access locked out. I'm told that
this should trip the bridge into a per-post retrieval, but it doesn't, and I have to do a catchup, and sample the area repeatedly in an attempt to get the posts.
Next time it happens there, I'll try and post the log here, if it would help :)

No - I do not work for Microsoft, or any of its contractors.
In my experience, the error message usually means that a thread has been deleted or moved, but my newsreader still thinks it is there. I noticed this a few days ago with the .reportabug forum (using the Community Bridge and Windows Live Mail). I Reset the group
in WLM, which usually fixes the problem. This time, that didn't work. Nothing will (re-)download, and I get error message 503. Catch Up suppresses the error message, but (obviously) I am unable to download any threads.
The error message from WLM is:
503 program fault - command not performed System.ServiceModel.CommunicationException: An error occurred while receiving the HTTP response to
