At 12:30 PST our engineers have noticed subpar network performance on node v7323. We are currently gracefully shutting the server down in order to apply a network driver fix.
At 12:44 PST our engineers have finished applying network driver updates and the node will be restarted in the next 5 minutes.
12:47 PST Node has been started, all VMs will start automatically in the next 15 minutes.
After 20 hours, no more issues observed. We are closing this issue at this time.
