Data Center & Colocation Services in Tempe: 7 Questions to Ask

Choosing a data center or colocation provider is one of the higher-stakes IT decisions a Tempe business can make — the wrong choice can mean downtime, data loss, or a contract you're stuck in for years. Before you sign anything, here are seven questions that cut through the sales pitch and get you real answers.

1. What Tier Level Is the Facility, and What Does That Actually Mean for Uptime?

Data centers are rated Tier I through Tier IV by the Uptime Institute. Tier III is the most common for commercial colo — it promises redundant components and around 99.98% uptime (roughly 1.6 hours of downtime per year). Tier IV adds fault tolerance and pushes closer to 99.999%. Ask for documented certification, not just a verbal claim. For most small-to-mid-size Arizona businesses, Tier III is sufficient; mission-critical healthcare or fintech operations may need Tier IV.

2. How Does the Facility Handle Arizona's Extreme Heat and Monsoon Season?

This question separates local experts from generic national providers. Phoenix-area summers routinely push 110°F+, which stresses cooling infrastructure far harder than data centers in cooler climates. Ask specifically:

• Cooling redundancy: Are there N+1 or 2N CRAC/CRAH units?
• Generator fuel contracts: During a prolonged summer outage, how long can on-site diesel generators run, and do they have a priority fuel contract?
• Monsoon preparedness: Arizona's July–September monsoon season brings dust storms (haboobs), lightning, and sudden power surges. Ask how the facility handles power conditioning and whether the intake filtration is upgraded for particulate levels common in the Valley.

A provider who can answer these questions fluently has clearly operated in the desert long-term.

3. What Are the Physical Security Layers?

Standard expectations in 2024 include:

• Mantraps or two-factor entry at the cage or cabinet level
• 24/7 on-site staffed security (not just cameras)
• Biometric or key-card access logs you can audit
• Visitor escort policies

Ask whether you'll receive access logs for your space on demand, and what their process is for removing former employees' credentials.

4. What Does the Contract Actually Lock You Into?

Colo contracts vary widely — month-to-month arrangements exist, but multi-year terms (typically 1–3 years) are common and usually carry better pricing. Watch for:

Also confirm how Arizona Transaction Privilege Tax (TPT) is handled — some providers include it in quoted rates, others add it separately. Get the all-in monthly number in writing.

5. What Connectivity Carriers Are Available On-Net?

Carrier diversity matters. A facility served by a single ISP is a single point of failure at the network layer even if the building itself is fully redundant. Ask for the list of on-net carriers and cross-connect pricing. If your business relies on low-latency connections to specific cloud regions (AWS US-West-2, Azure West US), ask whether the provider has direct cloud on-ramps or if traffic hairpins through an off-site exchange.

6. What Compliance Certifications Does the Facility Hold?

Depending on your industry, you may need your colo provider to support:

• SOC 2 Type II (most tech and SaaS businesses)
• HIPAA-compliant infrastructure (healthcare — common in Tempe given the ASU Health network and Banner Health proximity)
• PCI DSS (any business processing card payments)

Ask for the most recent audit report or attestation letter. A reputable provider will share a redacted version under NDA.

7. What Does Remote Hands Support Look Like at 2 a.m.?

"24/7 support" is a marketing phrase. Dig into what it means operationally:

• Is there always a trained technician on the floor, or just a security guard who can call someone?
• What is the guaranteed response time for remote hands requests?
• Is remote hands included in your plan, or billed hourly (rates typically range from $75–$200/hr depending on complexity)?
• Do they have a customer portal where you can submit tickets and monitor environmental sensors remotely?

If your IT team is small or you're running lean, responsive remote hands can be the difference between a 15-minute fix and a half-day outage.
