If you don't see this site come down soon, you can ask the handler on
duty, Marc, or Johannes, to activate a ThreatSTOP Emergency block on the
host. People using our service block inbound and outbound, and we have a
channel in place to have the ISC Handlers push out an emergency block,
if they detect a malware seed or C&C site that they want taken down,
that isn't responsive. We only let the handlers due this, so that the
proper incident response methods are followed.

attackers, check out www.threatstop.com
