Three years on GCP here... I’ve not once received one of these notifications. In my prior 7 years on AWS, these happened all the time, especially when you run a lot of VMs in different zones/regions (probably less visible if you are all in one zone).

Live migrations is amazing.

Now if only Google paid more attention to certain features of their GLB... amazing tech with showstopper bugs means amazing tech I can’t use. (Also means it’s not so amazing)
