Scheduled

We will be performing a live upgrade of the backend WEKA storage cluster to the latest LTS version. This will resolve some known issues and give us greater insight to address current issues with performance consistency / intermittent slow reads. The system is expected to remain online through the upgrade, though there may be some reduction in performance at various times as nodes are rebooted.
