This firewall, memorably, was involved (after it was serving live traffic) in a fat-finger incident in which I felt like I was setting a land speed record driving from Worcester to Waltham, because I managed to drop all traffic, with no out of band management access at that time. That was a stressful drive.
While prepping this post I went through a bunch of old stuff from our web site thanks to @internetarchive and I have a bunch of ideas for more stories to tell!
