An SLA is only as good as its remedies. Service credits that amount to a small fraction of monthly fees rarely reflect the real cost of downtime to the business relying on it.
Behind every application your customers touch sits a physical building full of power, cooling, and fibre. The choices made about that building quietly shape performance, cost, and risk.
The factors that actually move the needle
Headline pricing is the least reliable basis for comparison. Two facilities quoting similar rates can differ enormously once you account for power redundancy, cross-connect fees, remote-hands rates, and the small print around escalations and renewals.
Connectivity richness is frequently underweighted. A carrier-neutral facility with a dense ecosystem of networks and direct cloud on-ramps can save more over a contract term than a modest difference in the rack rate ever will.
What good looks like in practice
The strongest operators are transparent by default — uptime history, incident reports, and maintenance schedules are available without a special request. That openness is itself a signal worth weighing.
Good facilities make the boring things boring: predictable billing, clear escalation paths, and remote-hands requests that get done on the timeline promised, not the timeline hoped for.
Why it matters now
The market has split in two. Standard enterprise workloads still run comfortably at three to five kilowatts a rack, while accelerated-compute deployments are pushing twenty, fifty, even a hundred kilowatts. Those two worlds are priced and provisioned very differently, and conflating them is a common and expensive mistake.
Power has overtaken floor space as the binding constraint in most primary markets. Vacancy rates have fallen to record lows, and the practical effect is that capacity — particularly high-density capacity — increasingly needs to be reserved well ahead of when you actually need it.
A practical way to evaluate
Start with requirements, not providers. Pin down your power per rack, total committed capacity, connectivity needs, and the compliance regimes you answer to. That single page of clarity will shape every conversation that follows.
Model the whole cost, not the monthly line. Setup fees, cross-connects, bandwidth, growth headroom, and exit terms all belong in the comparison. The cheapest rack rate is rarely the cheapest deployment.
A short checklist before you sign
- Ask for real uptime history, not just the design tier
- Write down your power, space, and connectivity needs before you talk to anyone
- Ask what happens operationally when a single system fails, not just what the tier rating implies
- Leave headroom for growth, including higher-density racks down the line
- Read the exit and renewal terms as carefully as the price
The bottom line
There is no shortcut that replaces doing the homework, but there is a real payoff for doing it well: fewer surprises, better terms, and a partner that fits for the long run.
