For audit or other internal purposes, customer would like to know the physical location of WSS infrastructure.
Broadcom WSS product leverages Google Cloud infrastructure and locates its pop in various Google Cloud Compute (GCP) regions.
Google does not disclose the physical location of all of its data centers for security and confidentiality reasons, so this information is not available.
However, Google GCP infrastructure is audited and conforms to a number of standards and those audit documents are available via Google GCP documentation.
Physical location of Broadcom datacenters are documented on our "Web Security Service (WSS) ingress and egress IP addresses" KB (see the Compute region column).
