+- [x] xping all public router ips
+- [x] Open Grafana dashboard for OVN leaders
+- [x] Open Grafana dashboard for network metrics
+- [x] xping one vm on every compute node
+- [x] check ovn cluster status
+- [x] make sure ansible inventory covers all compute nodes
+- [x] make sure ansible inventory covers all network nodes
+- [x] make sure ansible inventory covers all ovn cluster database nodes
+- [x] Make sure network nodes are reboot proof
+- [x] Check ansible netconf for reboot proofness as well
+- [x] Check puppet status on all network nodes

+Xping: window 3
+Ansible playbook: window 4
+OVN db cluster nodes: window 4
+Neutron server tail: window 5

+Note
+- Moet ff iets slimmers om te xpingen. Freenet veelste veel pub router ips; liefst gwn 1 of ip per netwerk en compute node.
+	- Query OVN?
+- Ff proberen vast te leggen hoe we OVN databases automatisch kunnen checken op compleet up zijn, ipv arbitrair wachten en zelf kijken.
+- OVN upgrade 1: ongeveer om 2 uur begonnen, dingen recoveren volledig vanaf mijn POV: 2:09
+	- OVN db upgrade stap wacht: check -> lijkt allemaal goed, cluster status OK
+	- eerste ovn-controller upgrade (n01) -> shit blijft down hoe lang ik ook lijk te wachten: br-int connection timeout
+		- Besloten om toch gewoon proberen door te duwen
+		- Zodra ik continue met de volgende lijkt eigenlijk meteen br-int te connecten (toeval?) en gaan dingen recoveren
