As a general heads up Ubuntu has published new kernels which enable kernel page table isolation to address the meltdown vulnerability that made the news last week. The infra team is currently working through patching our Ubuntu servers to pick up these fixes. Unfortunately patching does require reboots so you may notice some service outages as we roll through and update things.
As a side note all of our CentOS servers were patched last week when CentOS published new kernels. We managed to do these with no service outages, but won't be so lucky with one off services running on Ubuntu.
Thank you for your patience and feel free to ask if you have any questions related to this or anything else really.
