In order to reduce the security risk of CVE-2016-2107 and raise our SSLLabs rating from "F" , we need to upgrade OpenSSL libraries on our public facing Nginx load balancers.
Will will conduct a rolling restart of the following services and corresponding load balancers. Each server will have its Nginx service stopped and started one at a time to make use of the new version of OpenSSL library.
You might receive notification from pingdom or some other alerting service informing you of outtage, but it should be very short and will be conducted starting at 03:00 to minimize impact.
You can follow the upgrade process in #site-infra-channel. Feel free to comment on this post if you have any questions or comments, by pinging @site-infra.
