During Puppet Camp Paris, I got the privilege to present the Continuous Delivery Workflow of TubeMogul's Operations Engineering Team. In few years, we went from few servers to over two thousands nodes fully managed by Puppet. In our presentation, we went over the challenges we faced as well as the implementation of our workflow to improve our day to day operation while still moving fast.
The International Earth Rotation And Reference Systems Service (IERS) announced that a positive leap second will be introduced on the last day of June 2015 (Official Bulletin C 49) making the day with 86,401 seconds.
In 2012, a similar event created major outages on most of the internet with only few avoiding problems. See this Forbes post from July 2012: +1: Google Aces 'Leap Second' While Reddit, LinkedIn And More Went Down Saturday.
It has been few days that some rumors were talking about a new SSLv3 vulnerability. It's been confirmed yesterday by the Google Security team as they released the details of the vulnerability. See CVE-2014-3566.
The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, aka the "POODLE" issue.
You must disable SSLv3.0 or CBC-mode ciphers with SSLv3.0 to mitigate the issue. You should make sure to do this for all your services, including third party services like Amazon AWS CloudFront.
A Bash vulnerability has just been announced, rated 10 on a scale of 10. The vulnerability is Network Exploitable. Patch Now.

You need to patch your systems now.
