We will send instructions on how to proceed soon. This pre-announcement is to help plan ahead. In the meantime please make sure to review your turn-up/migration plan.

Context:
As part of the Ikaria deprecation effort, Ganeti Virtualization SRE is turning down clusters hosted on Ikaria hardware. That hardware is deprecated and its turndown is planned to happen at latest by the beginning. 

You will have to either recreate your instance or delete it before the turndown date. In order to support this effort we will have replacement capacity available in MTV. Wait for further instructions before proceeding with the evacuation.


There are two shards and three afe servers in this list
