We will be taking host node CHI135KVM (one KVM VPS node in Chicago) offline shortly for an emergency maintenance (RAID card replacement). Customers on this host node were sent an email with additional information.
Estimated downtime is less than one hour. We will update this status incident once resolved.
UPDATE: The maintenance window is now completed and we are continuing to closely monitor the health of this server. If you are still experiencing any issues please open a support ticket and we'd be happy to assist.
