Just now one of our hypervisors crashed and left several VMs shut down for around 45 minutes. I have rebooted the host and service has been restored.

The affected VMs were:

web01  tools-k8s-worker-nfs-55  tools-k8s-worker-nfs-24  toolsbeta-test-k8s-worker-nfs-2  opensearch2  traffic-acmechief01  section-ranker  integration-agent-docker-1047  xtools-prod08  xtools-dev06  statanalyser  bullseye  deployment-ms-fe04  deployment-ms-be07  signwriting-swis-2022  signwriting-swserver-2022  mwparserfromhtml  video-nfs-1  striker-docker-01  twl-nfs-1  teyora  suggestbot-02  edit-types  soweego  quarry-dbbackup-01  pki-db
