On Thursday, January 23 at 15:00 UTC we'll be temporarily removing multiple hypervisors from service to replace failed hardware. This process will require rebooting the following list of virtual machines as we migrate workloads to different hypervisors.

Unfortunately, we had several hardware failures happen in a short time and need to take action as soon as possible.

Full list of instances that will be rebooted during Thursday's maintenance (shown as <project>: <instance name>):
