Scheduled
Instaclustr will be undertaking routine OS upgrades across our managed fleet, which include the Meltdown OS patch. Individual instances (nodes) will be rebooted in a rolling fashion. No overall impact on service availability is expected for clusters with RF3 (or higher) configured on keyspaces.

Customers running Spark will be individually notified of scheduled restart times.
