The Facebook outage aftermath
Fallout: People went two to three hours without knowing what their former high school classmates ate for breakfast. The world, astonishingly, did not end.
Fix: Facebook said the downtime was the result of a DNS issue that "prevented people who typed 'facebook.com' into their browsers from reaching the site" -- an issue that was easy enough to resolve. There were no signs that Anonymous had any involvement with the outage.
Facebook's flop affected only the regular desktop website; the company's mobile sites and apps remained online during the incident.
