The 30 minute outage that had Twitter all a-flutter with #FacebookDown trending took a major bite out of the company's $1.16 Million dollar an hour earnings - equating to about $500,000 or so in losses.

According to The Wire, this was the longest outage Facebook has experienced since 2010. That outage was caused by "an unfortunate handling of an error condition." (Translation: someone broke something.) Facebook hasn't yet disclosed what caused the incident.
