12 Mistakes First-Time Colocation Buyers Make
First-time colocation buyers most often go wrong on power, quote comparison and contract terms. Size usable kW from measured draw, send the same requirement to several providers, confirm carriers and cloud on-ramps at the building level, and get expansion rights, escalators and exit terms in writing before you sign.

Why first colo purchases go sideways
Renting data center space for the first time looks simple: pick a facility, sign, move in. In practice, colocation is quoted in units most teams have never bought before, such as committed kW, cross-connects, remote hands and escalators. Most first-time problems come from comparing the wrong things or leaving things out of the contract. Here are the mistakes we see most often, grouped by stage.
Planning mistakes
1. Sizing by space instead of power
Most first-time buyers count servers and ask for a number of cabinets. Providers, however, are often constrained by how much power they can deliver and cool per cabinet. If your gear draws more than the cabinet supports, you will need more cabinets or a different hall. Start with measured power. Colocation Power Requirements shows how to estimate kW, and our post on how many racks you need covers the space side.
2. Using nameplate power ratings
Nameplate ratings on power supplies describe a maximum, not typical draw. Sizing from them can push you into more committed power than you need. Measure real draw in your current environment where you can, then add a sensible margin.
3. Not deciding what must stay up
"We need redundancy" is not a requirement. Decide which systems must keep running during maintenance or a power event, and whether you need A and B feeds to every device. Colocation Power & Redundancy and Tier 3 vs Tier 4 explain what the terms actually mean.
4. Picking a market before checking connectivity
Being close to your office is useful, but the building must also have the carriers and cloud connections you need. Confirm these at the building level, not the metro level. Carrier-Neutral Data Center explains why carrier choice matters.
Shopping mistakes
5. Collecting only one quote
A single quote gives you nothing to compare. Request proposals from several providers, ideally across more than one building or market, using the same requirement. Larger markets such as Dallas, Phoenix, Ashburn and Chicago list many facilities on this site, so competition is easier to create there.
6. Comparing headline monthly prices
Two quotes with similar monthly totals can be very different once you include power overage rules, cross-connects, remote hands, one-time install charges and escalators. Put every quote into the same grid. Our guide to comparing colocation quotes shows how, and the pricing guide explains each charge.
7. Forgetting cross-connects and remote hands
Cross-connects to carriers and clouds, and remote hands for routine tasks, are separate line items at most providers. They are easy to leave out of a budget. See What Are Cross-Connects? and Remote Hands vs Smart Hands.
8. Skipping the site visit
Brochures describe the best hall in the building. Visit the finalists, see the actual space you would occupy, and ask to see maintenance and incident records. Use our Data Center Site Visit Checklist.
9. Accepting compliance claims without the reports
If you have compliance obligations, ask for the current audit reports and confirm they cover the specific building you are buying, not just the company. Colocation Compliance & Certifications explains what to request.
Contract mistakes
10. No expansion rights
If you expect to grow, get a right of first refusal or reserved option on adjacent cabinets or cage space, with terms written down. Without it, growth may mean a second, non-contiguous footprint or a move.
11. Ignoring the escalator and renewal mechanic
The annual escalator and the way pricing resets at renewal shape what you will pay over the full relationship. Read both before you sign. Colocation Contract Negotiation covers what to negotiate, and Colocation Contract Renewal explains what happens at term end.
12. Not reading the SLA exclusions
An SLA is only as useful as its definitions, measurement method and exclusions. Check how power and cooling are measured, what counts as an outage, what is excluded, and what credits you can claim. See Colocation SLAs and Contract Terms.
A first-time buyer checklist
If you are a startup or small team
Small teams have extra reasons to be careful: less time to manage a move, fewer staff on-site and less room for a surprise bill. A partial rack or a single cabinet in a well-connected building is a common starting point. Prioritize good remote hands, clear cross-connect pricing and flexible expansion terms over the lowest headline number. If your workloads are still changing quickly, compare against staying in the cloud first; see Colocation vs Cloud.
Next step
Avoiding these mistakes mostly comes down to sending a clear requirement and comparing real proposals. Request colocation quotes, or book a consult and we will walk through your first colo purchase with you.
Frequently asked questions
What is the most common mistake first-time colocation buyers make?
Sizing by space instead of power. Providers often limit how much power each cabinet can draw, so start from measured kW and then work out the cabinet count.
How many colocation quotes should I get?
Enough to create real competition, from more than one provider and ideally more than one building. Send every provider the same requirement so the quotes are comparable.
What costs do first-time buyers forget?
Cross-connects, remote hands, one-time install or cage build charges, power overage, and the escalator over the term.
Do I need to visit the data center before signing?
It is strongly recommended. A site visit lets you see the actual space, check power and cooling, review security and ask for maintenance and incident records.
What contract terms matter most for a first colocation deal?
Expansion rights, the annual escalator, the renewal pricing mechanic, SLA definitions and exclusions, and exit and de-install obligations.
Is colocation a good fit for startups?
It can be, for steady workloads that need specific hardware or predictable cost. A partial rack or single cabinet is a common start. Fast-changing workloads may suit the cloud better.
