The constraint is simple: buildings take years to deliver, and the chips inside them now change every year.
with Mach Eigen
An AI factory is a machine for turning capital into computation.
with Gilbert Faraday
Let me start with the observation that organizes everything else in this course.
with Gilbert Faraday
The schedule is the product now.
with Gilbert Faraday
A server drawing a kilowatt is, for practical purposes, a kilowatt heater that answers questions.
with Mach Eigen
Capital does not buy data centers.
with Gilbert Faraday
Power sets the ceiling.
with Mach Eigen
Start with a claim, because the whole course hangs from it: a data center is not one machine but two, and they are governed by different logic.
with Gilbert Faraday
For most of the industry's history, power followed the building.
with Gilbert Faraday
A press release about a data center is a promise.
with Mach Eigen
Start with the structure of the thing, because the structure explains everything downstream.
with Mach Eigen
A neocloud is a bet that four clocks will keep time together: the customer's contract, the chip's working life, the power at the site, and the loan that paid…
with Mach Eigen
Start with a claim and defend it: network architecture is the under-tracked constraint on AI compute delivery.
with Gilbert Faraday
Start with a plain observation: complex systems fail, and they fail in ways their designers did not anticipate.
with Gilbert Faraday
In March 2024, Equinix named its next chief executive nearly three months before she started.

States have always organized themselves around whatever resource their era treats as the master input.
with Gilbert Faraday
There is a tidy story the data-center industry used to tell itself.
with Gilbert Faraday
When people outside the industry picture a data-center siting decision, they picture engineers arguing about megawatts and water.
with Gilbert Faraday
Start with a simple observation that anyone who has managed a large construction program will confirm: the schedule almost never breaks because the money ran…
with Mach Eigen
Start with the structural fact: the entities that train frontier models have stopped renting infrastructure and started commissioning it.
with Gilbert Faraday
Start with the map, because the analyst world is not one thing.
with Gilbert Faraday
Every hyperscaler faces the same question for each new increment of capacity: do we build and own the facility, lease a purpose-built shell from a developer…
with Mach Eigen
Start with a clean separation.
with Mach Eigen
Export controls are one of the oldest instruments of statecraft, but the version that now governs computing is a recent and deliberate invention.

Start with a picture that will keep you honest for the rest of this course.
with Gilbert Faraday
Let me name the instrument before we use it.
with Gilbert Faraday
When people picture the buildout behind a new plant, a data center, or a grid upgrade, they tend to see concrete and steel.
with Mach Eigen
Cyber risk did not begin as its own product.
with Gilbert Faraday
Start with a claim that sounds like a metaphor and turns out to be an accounting identity: fiscal policy is the second power grid.
with Gilbert Faraday
Start with a fact that annoys people: the electric grid is the largest machine humans have ever built, and it has no meaningful storage.
with Mach Eigen
Start with the shape of the workload.
with Mach Eigen
Start with a claim and hold it through the whole course: a data center is not a destination, it is a node on a graph.
with Gilbert Faraday
Let me start with the thesis that runs through this whole course, because everything else hangs off it: failure is the cheapest intelligence you will ever…
with Mach Eigen
The accelerator isn't limited by math.
with Gilbert Faraday
Let me start with the number that reorganized the whole conversation.
with Mach Eigen
The data center you picture as a hall of servers is, physically, two machines fused together.
with Mach Eigen
Physical security for a data center is a layered system.
with Gilbert Faraday
Start with a single county in Virginia, because everything about how this industry maps itself onto geography starts there.
with Mach Eigen
Start with the physical fact and the money follows.
with Mach Eigen
A facility that can't be insured can't be financed.
with Gilbert Faraday
Before you argue about an incentive, learn what is being reduced.
with Gilbert Faraday
Before a company announces a new campus, it has to staff one.
with Gilbert Faraday
For most of the last two decades, a siting decision was fundamentally an engineering and economics problem.
with Gilbert Faraday
Let me start with a number that reframes everything.
with Gilbert Faraday
When people ask why a new data center cannot simply "plug in" to a grid that already runs surplus power at 3 a.m., the honest answer starts with a piece of…
with Mach Eigen
Open the lid of a modern AI accelerator and the first surprise is how little of it is the thing everyone talks about.
with Mach Eigen
Start with the claim the rest of the course defends: a large training cluster is a single machine, and its speed is governed by communication, not computation.
with Gilbert Faraday
Start with the arithmetic, because the arithmetic is what makes this course necessary.
with Mach Eigen
Every parametric contract rests on three moving parts, and the discipline of the product is to define each so tightly that no adjuster is ever needed.
with Gilbert Faraday
Start with a distinction that will organize everything else in this course: an accident is random, and an adversary is optimized.
with Mach Eigen
The early internet was engineered to route around obstacles, and its architects treated national borders as exactly that: obstacles.
with Gilbert Faraday
Let me start with a claim I can defend with a decade of transcripts: by the time a company issues a press release, the interesting information has usually…
with Mach Eigen
Data Center Infrastructure Management is a category with a precise remit.
with Mach Eigen
The AI build-out runs on a simple constraint: someone has to pay for the chips before the chips earn a dollar.
with Gilbert Faraday
FLAP-D is shorthand for Europe's five primary data-center metros: Frankfurt, London, Amsterdam, Paris, and Dublin.
with Gilbert Faraday
Start with a distinction that sounds pedantic and turns out to organise the whole field.
with Gilbert Faraday
Start with how land has been priced for as long as there has been a market for it.
with Gilbert Faraday
Let me start with the mechanism, because most confusion about data-center power dissolves once you follow the paperwork.
with Gilbert Faraday
Ask a developer what starts the clock on a data center and the honest answer has changed.

A finished data center is often described as if it runs itself.
with Gilbert Faraday
Let me start with the thing most practitioners get wrong.
with Mach Eigen
Start with a definition, because the term is abused.
with Gilbert Faraday

with Mach Eigen
Start with a correction.
with Gilbert Faraday
When a governor stands at a podium beside a corporate logo and names a number — jobs, investment, payroll — you are watching a communications event, not a…
with Gilbert Faraday
Let me start by clearing up a confusion that trips up even experienced infrastructure people: a data center's relationship with water is mostly about heat…
with Gilbert Faraday
Every recovery conversation eventually reduces to two questions, and the discipline of continuity planning is mostly the discipline of asking them in the…
with Gilbert Faraday
Expert site selection begins with an uncomfortable admission: the skills that win a single deal can lose a portfolio.
with Gilbert Faraday
The planning commission is the real interconnection queue.
with Gilbert Faraday
Start with the number that governs everything else in this course: the interconnection queue.
with Mach Eigen
The dominant narrative of the AI infrastructure boom has two protagonists: silicon and electricity.
with Mach Eigen
For a decade, the shorthand for siting a large data center ran through two questions: can you get the power, and can you get the water.

with Mach Eigen
Start with the physical fact.
with Gilbert Faraday
Let me start with a claim I can defend from the evidence: by the time a merger is announced, the people who will make it work have usually already been chosen.
with Mach Eigen
Start with the uncomfortable fact.
with Mach Eigen
A bare accelerator is a slab of silicon that can multiply matrices very fast and do almost nothing else on its own.
with Mach Eigen
Start with the number that dominates every other number in this market: hyperscaler capital spending.
with Gilbert Faraday
For most of the industry's history, the siting conversation ran in a familiar order.
with Gilbert Faraday
Every serious operator eventually notices the same thing: the report that landed in your inbox this morning, the one shaping the boardroom conversation this…
with Gilbert Faraday
Every outage leaves a record.
with Mach Eigen
Sovereign AI is sold as a policy achievement.
