Yes I have verified all the scheduling flags for our instances.
Preemptible: false
OnMaintenance: MIGRATE (only other option is terminate which happens far too often for any sizable shop to use and you lose the 60 second warning)
Key word being usually. Even if it's not a complete failure we have seen all sorts of fun from packet loss/latency spikes to seg faults.
I have no doubt things will improve but right now pd, network, and live migrations are pain points for our group in gce.

This isn't even a secret, it's fairly well-documented: https://cloud.google.com/compute/docs/instances/live-migration https://cloud.google.com/compute/docs/instances/live-migrati...
