RE: CodeGreen beta release (idq-patcher/antiCodeRed/etc.)

["Kayne Ian (Softlab)" <Ian.Kayne () softlab co uk>]

That is a policy adopted by some ISPs here in the UK, such as Blueyonder &
NTL - if they discover codered traffic from your IP they shut your access
down. Except I can see them reversing this policy the next time this
happens, due to the amount of complaints to both them and Trading Standards
(UK Government organisation that tries to prevent corporations ripping off
consumers) from ppl who have no clue what they are doing but know they've
lost access to "that internet thing I pay for". Time and money, time and
money....

Also just to the poster who made a comment about IIS availability and boxes
going down, surely if your IIS system is critical 99.9% you have it running
in a cluster of some shape or form? IIS goes down of its own accord all the
time, it doesn't need a worm to help it on it's way ;)
