Maybe -- we need more data to be sure.  But -- given that a lot of 
folks have patched systems over the last two weeks -- I suspect it's 
running out of "food".  Look at the graph from the last go-round at -- it leveled off, too.
(If the Worm is operating on UTC, the "stop" phase would have commenced 
at 2000 EDT.  Even if it ran on local time, Western European machines 
wouldn't quiesce until 1700.  The drop off starts well before that.)
