The site just went down again, awkwardly enough, only moments after they published their post-mortem on yesterday's outage.
Clearly, as their blog post indicates, they were unable to trace the root problem.
To me, the worst feeling in the world as a developer is when there's a major bug in your production site, and you can't figure out exactly why it happened. Then even after you get the site working there's that pit in your stomach of "what if it strikes again?"
I have a similar feeling toward my car's problems. I think it's the general issue of reproducibility that can cause such a feeling. You know the problem is there, but you're not sure of the cause, nor can you reproduce it reliably. Immediately, the issue becomes top priority because you don't know what to expect.
