Signing is not having capacity: 17 months between the contract and your data center

When your data center provider assures you that it has available capacity, you tend to assume you will be able to move your equipment within a matter of weeks. At the largest global operator in the sector, the average time between signing a contract and its contractual start during the third quarter of 2026 was 17 months. Seventeen months with the commitment signed, the money committed and the rack still nonexistent. This article explains what the figures published by operators measure —contracted backlog, reservations, gigawatts under construction— and what to ask so that the capacity they quote you arrives when you need it.

Three figures you need to read (and one you need to ignore)

The largest global data center operator published its third quarter 2026 results before the SEC on October 29, 2026: total revenue of 1,900 million dollars, 21% above the same quarter last year, and quarterly reservations of 855 million dollars of GAAP annualized rent at 100% participation, 627 million at the company level. The figure almost nobody cites is another one: the contracted backlog —contracts already signed that have not yet started— reached a record 2,500 million dollars of annualized base rent, and the average weighted delay between signing a new contract and its contractual start date was 17 months.

Backlog measures interest in future capacity, not the capacity you will have on the day you need it.

On the manufacturer side: the demand exists, but it does not arrive in time

The other side of the same coin was reported by the manufacturer. Vertiv published on October 28, 2026 net sales of 4,313 million dollars in the third quarter, 61% more than a year earlier and 55% organic growth; the Americas grew 75% and organic order growth surpassed 100%. Adjusted operating margin was 25.2% and 2026 sales guidance was raised to 14,650 million. CEO Giordano Albertazzi summarizes the moment: “we are in the middle of the largest infrastructure build in history and it is accelerating”.

The honest reading of both reports is uncomfortable: the demand is real, but with the manufacturer at 100% organic orders, the equipment delivery date decides your start, not the available square meter.

The range that actually applies to you: from 0 to 1 MW

There is one figure that does speak to customers like yours. In the breakdown the company itself publishes, the 0 to 1 MW category contributed 129.6 million dollars, 20% of total reservations at its share; interconnection, 22.2 million, 4%; and the range above 1 MW, 474.2 million, 76%. The sector narrative is “hyperscale or nothing”, but a fifth of reservations came from the enterprise range, exactly where Noxtel operates. And there is one figure with a price reading: renewals rose 11.8% on a cash basis. Waiting has a cost, and that cost is already measured.

For the rest of the layers of the offering —what a Tier is and what an SLA covers— we explain it separately in What is a Tier I, II, III and IV SLA.

Load size also matters: in Mexico data center electricity demand will multiply sixfold towards 2031, as we break down in Data centers in Mexico: electricity demand will multiply ×6 by 2031.

The five questions to audit the capacity they quote you

If the conversation with your provider stays at “we are three hundred data centers and we have capacity”, there are five questions that change it.

In Mexico, the evidence is an opinion, not a promise

In Mexico, the difference between a promise and evidence is written into law. The Infrastructure Quality Law establishes, in its article 64, that imported products or services must have certificates, opinions or test results from an accredited and approved Conformity Assessment Body, or from a foreign third party with a mutual recognition agreement; and its article 30 requires that every Mexican official standard include the conformity assessment procedure according to its risk level. On October 28, 2026 SENER issued the Guidelines governing the approval, updating and oversight of those bodies, on the basis of that law.

For a white room the translation is one to one: the opinion is issued by an accredited third party, not by the provider who sold you the equipment. Request it in writing with the standard, the body and the scope of what was evaluated, and include it in the start-up list together with the environmental permits and the supply contract. The four permits a data center in Mexico must resolve before operating are detailed in Environmental compliance for data centers in Mexico: the 4 SEMARNAT permits.

Verdict

Three numbers to take away: 17 months is the average delay between signing and starting, and it is the number against which you must compare your date; 20% is the weight of the 0 to 1 MW range in one quarter’s reservations, meaning you are not at the margin; and 2,500 million dollars of contracted backlog do not equal an energized megawatt. What does work is concrete: a contractual start date in writing, conformity evidence signed by an accredited body and a Tier certificate per room.

If your project has a committed start date and nobody gave you the contractual start date in writing, a capacity audit is worth it: at Noxtel we review the contract, the power plan, the Tier plan and the conformity evidence, so that the date you promise your business is one your provider can sustain. Request the capacity assessment for your data center.
