How to Compare Colocation Quotes Side by Side

Why colocation quotes are hard to compare

Two colocation proposals for "ten cabinets" can describe very different products. One may quote usable IT power with A/B feeds, the other may quote breaker capacity on a single path. One may bundle a block of remote hands and a few cross-connects, the other may bill each one from day one. One may assume a three-year term, the other a five-year term with a higher escalator. When you line up the headline monthly figures, you are often comparing assumptions, not prices.

This guide is for buyers who already have (or are about to receive) two or more proposals and need to pick a finalist. If you still need to understand what each line item means, start with the Colocation Pricing Guide. If you have not yet issued a structured request, use the Colocation RFP Checklist so every provider answers the same commercial sheet.

Step 1: Lock a single requirements baseline

Before you open a spreadsheet, write down the one set of requirements every quote must satisfy. If a provider quoted something different, send it back and ask for a re-quote against the baseline rather than adjusting their numbers yourself.

Your baseline should state:

• Footprint: cabinet count, cabinet size, cage or suite, and any adjacency requirement.
• Power: usable IT kW at day one and at month 24, sustained kW per rack, and redundancy (for example A/B feeds). The Colocation Power Requirements guide shows how to build this brief.
• Cooling: the density band you need supported in the specific hall, not the building average.
• Connectivity: named carriers, cloud on-ramps and the number of cross-connects at go-live.
• Services: expected remote hands usage, after-hours needs and shipping/receiving.
• Term and date: contract term, ready-for-service date and acceptable ramp schedule.
• Compliance: reports or attestations you need for the specific building.

Step 2: Normalize every quote into the same grid

Rebuild each proposal into a single comparison grid. Do not rely on each provider's own summary page; transcribe line items so hidden assumptions become visible.

"Ask the provider" is intentional. Pricing varies by market, building, hall, density, term and timing, so fill each cell only with the figure written in that provider's proposal.

Project the full term, not month one

Once every cell is filled, project each recurring line across every month of the term, apply that provider's escalator to the components it covers, then add one-time charges. The result is a total contract value for the same scope. Dividing that total by the usable kilowatt-months you will actually receive gives a single normalized unit cost you can compare across providers, and it exposes a low-monthly proposal with heavy one-time fees, or a low-install proposal with a steep escalator.

Keep an exclusions column

For every quote, list what is not included: cage build, power whips, cabinet hardware, security badges, after-hours access, shipping, de-install at exit. A proposal that looks competitive often simply excludes more.

Step 3: Score what the price does not show

The lowest normalized cost is not automatically the best award. Score each finalist on the risks that can cost more than any line item.

Weights are a starting point; a regulated workload may make compliance a pass/fail gate, while a fast deployment may make delivery certainty decisive. Agree weights internally before you open the price columns so the scoring stays honest.

Step 4: Watch for common quote red flags

• Headline kW that is not usable kW. Ask whether the number is breaker rating, derated circuit capacity or usable IT load.
• Different terms per provider. A longer term can hide a higher total even with a lower monthly figure.
• "Market rate" expansion. Expansion at then-current pricing is not an expansion right.
• Renewal at list. Some agreements revert to list pricing at renewal; see Colocation Contract Negotiation.
• Cross-connects quoted as "available." Availability is not a price or a lead time. The What Are Cross-Connects? guide covers what to confirm.
• Expiry pressure. A short quote validity window is normal, but it should not force you to skip diligence. Ask for a written extension if needed.

Step 5: Compare across markets, not just providers

If your workload can live in more than one metro, compare a shortlist across markets. Available power, delivery timelines and carrier density can differ sharply between locations. Buyers commonly compare Dallas against Phoenix, or Ashburn against Chicago or Atlanta, when latency and network requirements allow. Use the same baseline for every market so the comparison stays fair.

The same grid works when benchmarking a renewal against alternative providers at the end of a term.

Step 6: Run a best-and-final round

With a normalized grid and a risk score, narrow to two or three finalists and ask each for a best-and-final offer against the same baseline and the same contract redlines. Negotiate in parallel so no provider sees you as committed. Ask each finalist to confirm in writing: the ready-for-service date, the usable power per cabinet, the renewal mechanic, the escalator cap and the expansion terms. Those confirmations are what you will enforce later.

Before the award, use a data center site visit checklist to verify what each finalist claimed in its proposal.

If you want help running this round, weigh using a colocation broker vs going direct.

Questions to ask providers

1. Is the quoted power usable IT load, and is redundancy (for example A/B feeds) included in that figure?
2. Is power reserved, metered or hybrid, and how is draw above the commitment billed?
3. Which hall and cabinet positions are included, and is cooling confirmed at our density there?
4. How many cross-connects are included, what is the recurring and one-time charge for additional ones, and what is the typical lead time?
5. What remote hands time is included, and what are after-hours and emergency rates?
6. Which one-time charges can be waived or capped for a longer term?
7. What is the annual escalator, is it capped, and which components does it apply to?
8. What is the renewal pricing mechanic, and can it be fixed now?
9. What adjacent space and power can you reserve for us, for how long and at what commercial terms?
10. What is the ready-for-service date, and what remedy applies if it slips?
11. What does this proposal exclude that other customers usually add later?
12. How long is this quote valid, and what could change it?
