Linux crippled by a second
If you administer Linux servers or network appliances running Linux under the hood, you may have had to deal with high CPU utilization as a result of the Leap Second that was introduced this past Saturday. In fact, as a result of this leap second and some key software not being equipped to handle it, Amazon Web Services and many other web sites took a performance hit.
If you haven't heard of a leap second before, it's simply the addition of one second to the UTC clock to realign time with solar time.
So, if you are running Linux servers or appliances such as Infoblox, you might want to schedule a reboot to get this issue resolved (if you haven't already). Hopefully in light of the recent happenings, vendors will take action and patch their systems to better handle future leap seconds.
