    We have now analyzed a copy that we caught - it is also confirmed CRv2.

    You are right.  But looking at the growth curves, it was fairly close to
    saturated by the time that happened.  
    
    This time the worm is not going to mode switch until the 20th.  So it's going to
    saturate and then all the infected hosts are going to sit and spray the Internet
    with probes until they get fixed.  Rebooting won't help much since it will only
    be an hour or two until the host gets infected again.
    
    Stuart.
