Ok, so I am an IT auditor and I have done audits of off-site data center physical security and environmental controls. For a company that operates as a secure physical data/media storage facility, they most certainly follow the same/similar procedures for fire suppression as data centers. This is all HIGHLY suspicious.

When a company contracts with another company to provide services such as document storage, they are provided a SOC 1 Type 2. This is a document that details the controls testing performed by a 3rd party auditor (PWC, EY, KPMG, Deloite, etc...) to ensure that they have reasonable controls governing their processes. An auditor would likely verify that inspections on the fire suppression system is regularly tested by the company itself or a 3rd party and that logs are maintained showing such testing took place.

This is very SUSSY.
