Then you'd better reach over to all of your upstream routers and just pull
the plug, since you are likely to see Sapphire packets from here on in, on a
regular basis.
Better is to do the whois lookup and send pre-formatted e-mail about the infected server as people did after Code-Red.

Of course, if blocking "irresponsible isp's" is really your agenda, you'd
better start blocking those with Code Red/Nimda, Slapper, etc...

Enjoy your private corner of the world, devoid of connectivity...
