Several days ago, we became aware of a security vulnerability impacting x86 and others.
Due to the criticality of this bug, our Security team proactively took the decision to perform a major security update on all our hypervisors (ARM & X64).
We will perform a security update tomorrow of all impacted hypervisors and will need to reboot servers running on top of them.
A maintenance window has been scheduled between the 01/04/18, starting at 12 am IST and the 01/06/18, ending at 12 am IST.
We will reboot cluster one at a time to limit downtime on your infrastructure.
We sincerely apologize for the short delay of this notice, we believe security and privacy is crucial on cloud platforms and we decided today to trade some availability in favor of security.
