Instance logs missing after instance is recreated due to health check failure

We are running instance group with multiple instances. Logging works just fine when the instance is running, we can go back to days. However if for some reason instance health check fails and it has to be recreated, all logs before the "compute.instances.repair.recreateInstance" event are just completely gone so we cannot even debug why the instance health check failed as no logs exist. Am I missing something here?
