A showstopping perfmon counter
Dogfooding and Showstoppers. Figuring out what has happened in situations like this is both an art and a science. Since the server farm is located somewhere other than Redmond, you have to investigate everything remotely. All you have to figure out what went wrong are the perfmon logs and a raw memory process dump before it terminated (since these production servers had no debuggers attached). Analyzing them is a bit like a TV episode of CSI -- involving forensic science (what perfmon counter showed what and when) and a bit of detective work (trying to figure out what happened over the course of a day's run -- in particular in the last few minutes and seconds before things started going bad).
