Our first provider to respond to this is Scaleway. They have a maintenance window on 2018-01-05 from 7 am to 7 pm UTC. We don't know which servers will be affected or when. We have formed an emergency response team to handle these. We're awaiting info from other providers and patches from OS vendors.
