Dossier 05 / Physical computing

Look beyond
the capacity headline.

Separate the facility, the network, the component and the service. A better computing-infrastructure note begins by defining what is being measured and where the claim stops.

05.01 / Digital businesses have physical boundaries.

Installed and utilized are different

Record the unit and scope of a capacity statement. Ask which parts are installed, available, contracted or used, and leave undisclosed quantities unknown rather than filling them in.

05.02 / Observation prompt

Where does the claim stop?

Draw the network boundary in one sentence. A connector photograph cannot establish speed, performance or compatibility; each claim needs evidence about the system it describes.

Question to carry forward

Which part of the network is in scope, and what evidence supports the stated performance?

Network boundary · performance claim · evidence

Take this question to your watchlist

Photograph context

No cable category, bandwidth, security, compatibility or network-performance claim.

Gold traces and holes cross the surface of a dark blue printed circuit board. — Know which component is being discussed before comparing businesses.Vishnu Mohanan / Unsplash (opens in a new tab)

05.03 / Observation prompt

Identify the component

This is a bare printed circuit board, not a chip or AI accelerator. Use the distinction to ask whether the business designs, fabricates, assembles or operates the component under discussion.

Question to carry forward

Is the business being described a designer, fabricator, assembler or infrastructure operator?

Photograph context

This is a bare printed circuit board, not a chip, AI accelerator or semiconductor-fabrication facility. No issuer association.

05.04 / Observation prompt

Physical limits need sources

The photograph shows rooftop cooling equipment on a commercial building, not a verified data center. Use it only as a prompt to investigate the actual facility's physical constraints.

Question to carry forward

Which primary source establishes the actual facility constraints and energy assumptions?

Facility identity · constraints · energy assumptions

Take this question to your watchlist

Photograph context

Source identifies a commercial-building roof, not a verified data center. Generic cooling illustration only; no efficiency or energy-use claim.

05.05 / Observation prompt

Reach is not service quality

Keep coverage, capacity and service quality as separate lines in the note. Decide which source would support each one rather than treating a broad reach claim as proof of a specific experience.

Question to carry forward

Are coverage, capacity and service-quality claims being kept separate and sourced?

Coverage · capacity · service-quality measure

Take this question to your watchlist

Photograph context

No named operator, coverage, generation, speed, health or service-quality claim.

Leave with one better question

What does the capacity claim include, and what remains unmeasured?
