[MTL] An hypervisor rebooted

An hypervisor rebooted on the MTL region. This hypervisor only hosts some of the FSBucket add-ons as well as some DEV MySQL add-ons. We are investigating the root cause and start restoring the service.

EDIT 16:45 UTC: The services are available again. The issue most probably comes from an ongoing electrical maintenance. This server was located in room B710: https://network.status-ovhcloud.com/incidents/m9fzvt0nd8jm. We will follow up with OVH to get more information. In the meantime, we'll keep an eye on the maintenance status.
