As related to me by a senior systems developer, many popular Java sites
crash due to a Leap second bug which happened last night as the atomic
clocks, world wide jumped a second. Sites using Hadoop and the Apache
Cassandra databases were also affected. But many of the larger sites like
Google had already anticipated the error and had already morphed that extra


Sites like Mozilla went down and Reddit was still down when last looked.
Sites also affected were StumbleUpon, Yelp, FourSquare, and LinkedIn and so

It appears that this error was well known but many systems did not take the
bug seriously. I guess Oracle had better get to work.
