Investigate traffic to the git VMs
Now that websockets / git-ssh / git-https has been migrated to the Kubernetes, and all git VMs are configured as backup servers, we should not see any requests being sent to the git fleet.
this does not appear to be the case currently: https://log.gprd.gitlab.net/goto/2b71d289ca24ba54012588e3560b4c04
We can also see that git gke backends are going down occasionally, which corresponds to the traffic being sent to the
GKE servers in HAProxy should be available 100% of the time, do these down events correspond to deployments? Something else?
We need to investigate this before removing the git fleet as backup servers.
