Summary

As the Leap Second approaches on June 30, 2015, adding an extra second to Coordinated Universal Time (UTC) to keep it aligned with the mean solar time, IT infrastructures face potential challenges, particularly within Linux-based systems. The 2012 Leap Second caused significant disruptions, including high CPU usage on production servers, affecting major companies. To mitigate these issues, Linux vendors like RHEL/CentOS, Ubuntu, and SLES/OpenSUSE have released guidelines for preparing systems, and Elastic advises following these recommended procedures instead of untested solutions. Additionally, cloud providers such as Amazon and Google Cloud Platform have offered specific guidance for managing the Leap Second within their services.
