For clarity (as I struggled with the title), Drew did a 580,000 vcpu run this weekend (as an update from his 220,000 run previously). We decided to include the monitoring graph in the hopes that folks here wanted to see how quickly he brought them up, how long it ran, etc. and explicitly included the $20k number since we missed it last time.
Thanks for all the feedback, and onwards to 1M.
Disclosure: I work on Google Cloud and helped out with this.
