Just a small correction: it's not about "your work vs Google's", it's about regular VMs versus preemptible. There's no special code to give Googlers (or Alphabet Characters) special treatment with regards to preemption. The chrome clusterfuzz folks are standing side by side with you.
Disclosure: I work on Google Cloud (and launched Preemptible VMs).
