I sure am. Remote root exploits have been announced within the last few weeks for several of the most widely used DMZ network services: Apache, OpenSSH, and now the resolver libraries used in the nearly ubiquitous ICS BIND (among other things). It's been crazy trying to get all the servers I'm responsible for updated without breaking anything or causing loss of service. Unfortunately I think we're going to see a lot of hacked systems over the next several months. I hope things calm down a little so I can take a well-deserved long weekend after the 4th.
