Who would have thought a mere second could cause so much trouble?
Some of the world's most popular web sites crashed on Sunday after a "leap" second was added to the clock by international timekeepers, it has been revealed.
Sites such as Reddit, FourSquare, Yelp, LinkedIn, Gawker and StumbleUpon all experienced problems simultaneously on Sunday after the extra second was added to Universal Coordinated Time (UTC). The extra blip in time played havoc with the sites' source code and also caused servers to crash, leaving the sites down and unaccessible for hours, experts reveal.
The extra second is added to UTC—the benchmark time agreed internationally—every few years to keep it in line with the time as determined by the wobble in the Earth's rotation.
