Well, thank you for continuing to try, Mars! I thought it odd as well, although I still don't know nearly as much as you about this. Intermittent problems are the worst!
By the way, I wasn't paying close attention, but it seems that most, if not all of the times received the error, I was using IE. I also use Firefox and Opera (12.16), however, so it might have happened on these as well. I wouldn't think a 200 packet, or anything else could be mistaken for a 301, but I suppose it might be something to keep in the back of our minds.
