On Tuesday, January 23 at approx. 14:50 PST we will be performing an unscheduled maintenance on the below referenced nodes in order to prevent performance degradation.
Originally we planned to perform this maintenance after final BIOS updates addressing the Spectre vulnerability become available from our hardware vendors. However after today's communication from Intel it is clear that it will take at least a few more days - if not weeks - before we receive final BIOS updates. Meanwhile, we want to restore stability of our services in a predictable amount of time, so today we will be applying a few fixes to the remaining nodes in order to achieve that.
Each VM will be gracefully shut down one by one for a period of approx. 30 minutes to apply kernel updates on the hardware nodes. After that all VMs will be started again.
19:30 PST: All updates have been completed, all affected VMs have been restarted.
