Two hard days of work, including migrating a server at midnight. A server that noone really knew exactly what it did!
You see, lots of apps went through it. Weird business custom proprietary apps for several companies.
So, what had to be done? make another one of those evil contraptions work. But apparently noone found a way to pile another hack on the hacktower, and my job was to clean up the mess.
Well, they haven't called me yet, so either it worked, or the guy that I gave my number was fired ;-)
