Choosing the wrong colocation provider is one of the most expensive mistakes in Bitcoin mining. Locked into a bad contract with hidden fees, unreliable uptime, or inadequate infrastructure, you lose money every hour your miners sit idle or overpay for power you could source cheaper elsewhere.

This checklist distills the evaluation process into the specific questions, red flags, and deal-breakers that separate professional hosting operations from the growing number of undercapitalized facilities that cannot deliver on their promises.

Power Rate Structure: The Numbers Behind the Number

Every colocation provider leads with a power rate. That number means nothing without understanding what it includes and excludes.

All-In vs Base Rate

An “all-in” rate of $0.075/kWh that covers power, cooling, management, and physical security is a fundamentally different proposition than a base rate of $0.075/kWh plus separate line items for cooling surcharges, management fees, network costs, and security deposits. Calculate the true all-in cost before comparing providers.

Rax Mining hosting starts at $0.075/kWh with transparent rate structures across 27 U.S. states. Understanding exactly what your rate covers is the first step in any provider evaluation.

Rate Escalation Clauses

Check whether the contract allows the provider to pass through utility rate increases. Some contracts lock your rate for the full term. Others include escalation clauses tied to the local utility tariff, PPI, or CPI. A contract that starts at $0.075/kWh but includes uncapped utility pass-through could cost $0.08/kWh within a year if the local grid operator raises industrial rates.

The best contracts either lock rates for the full term or cap escalation to a fixed annual percentage. Uncapped pass-through clauses shift all energy price risk to you while the provider bears none.

Minimum Commitment and Take-or-Pay

Most colocation contracts include a minimum power commitment — you pay for a reserved capacity whether your miners are running or not. A 500 kW minimum commitment at $0.065/kWh costs $32,500/month regardless of how much power you actually consume.

Evaluate whether your fleet realistically fills the minimum commitment from day one. If you are scaling up gradually, negotiate a ramp schedule that aligns your minimum commitment with your deployment timeline. Take-or-pay clauses without ramp provisions are a red flag for operators who have not planned their capacity correctly.

Uptime and SLA Terms

Uptime Guarantee Percentage

Industry-standard uptime SLAs for mining colocation range from 95% to 99.5%. The difference between these numbers is dramatic: 95% uptime allows 36.5 hours of downtime per month. 99.5% allows only 3.65 hours.

More important than the percentage is the SLA credit structure. What compensation do you receive when the provider fails to meet the guaranteed uptime? Best-in-class providers offer power credits proportional to downtime. Weak SLAs offer credits only for “unscheduled” downtime and define maintenance windows so broadly that most outages are classified as scheduled.

Planned Maintenance Windows

Ask how many hours per month the provider reserves for planned maintenance, and whether planned maintenance counts against the SLA uptime calculation. Some providers exclude up to 8 hours per month of planned maintenance from SLA calculations, meaning their “99%” SLA actually guarantees only 97.9% real uptime.

Force Majeure Definitions

Force majeure clauses excuse the provider from SLA penalties during events beyond their control. Reasonable force majeure covers natural disasters and grid-wide utility outages. Unreasonable force majeure clauses include vague language about “equipment failure” or “supply chain disruptions” that effectively let the provider escape accountability for their own infrastructure failures.

Facility Inspection Checklist

Never sign a colocation contract without an in-person facility inspection. If the provider will not allow a site visit, that is an immediate disqualifier.

Electrical Infrastructure

• Main utility feed: What voltage, amperage, and phase configuration feeds the facility? Is it a dedicated utility feed or shared with adjacent properties?
• Backup power: Does the facility have generator backup? What is the transfer time? How much fuel is on-site? Is the generator tested under load monthly?
• Distribution: Are PDUs metered per outlet? Can you monitor your power consumption independently?
• Transformers and switchgear: Are they properly rated for the facility load? When were they last inspected? Is there expansion capacity?

Cooling Systems

• Cooling method: Air cooling, immersion cooling, or hydro cooling? What ambient temperature does the facility maintain?
• Redundancy: If one cooling unit fails, can the remaining units maintain safe operating temperatures? What is the facility’s thermal runway time?
• Airflow design: Is there proper hot aisle/cold aisle separation? Are blank panels installed in empty rack positions?

Physical Security

• Access control: Key card, biometric, or guard-gated? Who has access to your equipment besides you?
• Surveillance: 24/7 camera coverage with how many days of retention?
• Perimeter: Fencing, lighting, and intrusion detection for outdoor container deployments

Network and Monitoring

• Internet connectivity: Redundant ISP feeds? What bandwidth per miner?
• Monitoring access: Can you access your miners remotely 24/7? Does the provider offer monitoring dashboards?
• IP allocation: Static IPs included or additional cost?

Insurance and Liability

Colocation contracts allocate risk between provider and customer. Understanding this allocation prevents devastating surprises.

Provider Insurance Coverage

Ask for a certificate of insurance. The provider should carry, at minimum, commercial general liability, property insurance covering the facility and its infrastructure, and business interruption insurance. If the facility burns down or floods, provider insurance should cover rebuilding the infrastructure — but it will not cover your mining hardware.

Customer Equipment Insurance

Your mining hardware is almost never covered by the provider’s policy. You need your own inland marine or equipment insurance policy that covers your miners while located at the colocation facility. Verify that your policy covers equipment at a third-party location and that the colocation contract does not include waivers that void your coverage.

Liability Caps

Most colocation contracts cap the provider’s total liability to a fixed amount (often equal to one month’s fees) regardless of the damage caused. If a provider’s electrical failure destroys $500,000 worth of your mining hardware and their liability is capped at $15,000 in monthly fees, you absorb the remaining $485,000 loss. Negotiate liability caps upward, or ensure your own insurance covers the gap.

Scalability and Expansion

Available Capacity

Ask about current facility utilization and expansion capacity. A facility running at 90% capacity cannot accommodate your growth without infrastructure upgrades that may take months. Ideal providers have clear expansion roadmaps with committed utility capacity for future phases.

Right of First Refusal

Negotiate a right of first refusal on adjacent capacity as it becomes available. This prevents competitors from locking up expansion space that you need for growth. The best contracts guarantee expansion capacity at locked rates within a defined timeframe.

Multi-Site Options

Providers operating across multiple geographic locations offer diversification benefits. If one site experiences extended downtime, you can potentially relocate miners to another facility. Ask whether the provider can facilitate inter-site transfers and whether your contract terms port across locations.

Contract Red Flags

These terms should trigger serious negotiation or disqualify the provider entirely:

• Auto-renewal without notice: Contracts that automatically renew for multi-year terms unless you provide notice 90-180 days before expiration lock you in if you miss the window.
• Unilateral rate changes: Any clause allowing the provider to change rates with less than 90 days written notice.
• Equipment liens: Some contracts give the provider a lien on your mining hardware for unpaid invoices. This means they can refuse to release your equipment if there is a billing dispute.
• Vague termination fees: Early termination penalties should be clearly defined. Penalties calculated as “remaining contract value” make it prohibitively expensive to leave a bad provider.
• No audit rights: You should have the right to verify your power metering independently. If the provider refuses metering audits, you have no way to confirm you are being billed accurately.
• Exclusivity clauses: Some contracts prohibit you from hosting miners at competing facilities. This limits your diversification options and negotiating leverage.

The Evaluation Conversation: Questions to Ask

Before signing any contract, have direct conversations with the provider’s technical and operations teams. Scripted sales responses reveal less than unscripted technical discussions.

1. What was your longest unplanned outage in the past 12 months, and what caused it?
2. How do you handle curtailment events — do you participate in demand response programs, and if so, how does that affect my uptime?
3. What happens to my miners if you go out of business? Is there a wind-down plan?
4. Can I bring my own network monitoring and security tools, or am I required to use yours?
5. What is your current customer retention rate? How many customers have left in the past year and why?
6. Who is your utility provider, and what is your contracted capacity versus actual consumption?
7. Do you allow custom firmware on hosted miners, or do you require stock firmware?
8. What is your staffing model — how many technicians are on-site during each shift?

Making Your Decision

After evaluating multiple providers against this checklist, create a weighted scorecard. Weight power cost heavily (it is your largest ongoing expense), but do not let the cheapest rate override concerns about reliability, contract terms, or facility quality. A provider offering $0.045/kWh with 90% uptime costs you more in lost revenue than a provider at $0.065/kWh delivering 99% uptime.

The ROI model for your operation should incorporate realistic uptime assumptions, not best-case scenarios. Run your numbers at 95%, 98%, and 99% uptime to understand the financial impact of provider reliability on your actual returns.
