Kind of an inside joke. On an emergency conference call regarding a recent and serious Microsoft vulnerability, we set a very stringent patching deadline. Someone piped up "well, what if it gets exploited in the next 24 hours?". A colleague responded, "Well the data center could get swallowed by an earthquake in the next 24 hours." A very succinct and effective illustration of the likelihood of certain risks.
