Hmmm!!! Something's amiss because I'm still getting the same garbage headers. Also, the forums at the primary site, sudoku.org.uk, result in an unavailable page error when I try to access them.
The kakuro branch of this same sudoku.org.uk, http://sudoku.org.uk/kakuroflash/kakuro.html, also is having problems. Normally this url generates a new puzzle every day, at about midnight or 1:00 a.m. Today (12-10-2011), however, the most recent puzzle is yesterday's (12-9-2011).
It appears the Kakuro branch, at least, is now working again. As of 12-12-2011, the last three days' missing puzzles (in fact the last ten, as usual) are now available for viewing or printing.
