I did make a post below actually a few hours back and will copy and paste it below for reference. Rest assured that we are working on this one and are in contact directly with the customer. We hope to have more of an official response soon.
from below: I work here in Google Cloud Platform Support. First, we sincerely apologize for the inconvenience caused by this issue. Protecting our customers and systems is top priority. This incident is a good example where we didn’t do a good job. We know we must do better. And to answer OP’s final message: GCP Team is listening.
Our team has been in touch with OP over what happened and will continue digging into the issue. We will be doing a full review in the coming days and make improvements not only to detection but to communications for when these incidents do occur.
