It looks like that it is a central service @ Google called Chemist that is down.
"Chemist checks the project status, activation status, abuse status, billing status, service status, location restrictions, VPC Service Controls, SuperQuota, and other policies."
-> This would totally explain the error messages "visibility check (of the API) failed" and "cannot load policy" and the wide amount of services affected.

EDIT: Google says "(Google Cloud) is down due to Identity and Access Management Service Issue"
