When colocation space goes unused
Most colocation contracts run three to five years. A business can change a lot in that time. These are the situations we see most:
- A workload moved to the cloud before the colo term ended.
- A merger left two companies with two cages in the same market.
- An AI project was cancelled or delayed after the power was committed.
- The company bought power for growth that has not arrived yet.
- The company consolidated into a larger site and the old one sits half empty.
In each case you keep paying the monthly charge for space and power you do not use. Placing that space with someone else stops some or all of that cost.
Three ways out of a colocation commitment
| Option | How it works | Your position after |
|---|---|---|
| Sublease | A subtenant uses the space and pays you, or pays toward your bill, for the rest of the term. | You stay on the contract with the operator. Your cost drops by what the subtenant pays. |
| Assignment | The operator moves the contract to a new company, which takes it over in full. | You are released if the operator agrees to release you. Some operators keep the original tenant liable. |
| Rework the deal | The operator takes the space back for a fee, shrinks your footprint, or moves you to a smaller space or another of its sites. | Depends on the deal. It works best when the operator has buyers waiting for that space. |
We work all three. Often the right answer is a mix: give back part of the space, sublease the rest, and keep what you still use.
What the operator has to approve
Almost every colocation agreement needs the operator's written consent before you sublease or assign. Read your master services agreement before you promise anything to a subtenant. These are the terms that usually decide what is possible:
- Consent clause. Whether the operator may refuse, and on what grounds.
- Credit review. Many operators check the new company's finances before they agree.
- Use limits. Some agreements forbid reselling space, or limit who may use it.
- Liability. Whether you stay responsible if the subtenant stops paying.
- Access and security. Who may enter the cage, and how badges and access lists change.
- Power billing. Metered power often stays on your account unless the operator splits it.
- Cross-connects. Whether existing circuits can move to the new company or must be ordered again.
We read these terms with you first. Then we tell you which option is realistic before we bring anyone to the table.
What makes colocation space easy to place
Space in a tight market fills fast. Space with little time left on the term is harder. These are the factors a subtenant weighs:
| Factor | Easier to place | Harder to place |
|---|---|---|
| Market | Markets with little open space, such as Northern Virginia, Dallas and Chicago | Markets with plenty of new supply |
| Power density | High kW per cabinet, especially space that can take GPU racks | Low-density space in an older hall |
| Time left | Twelve months or more, with a renewal option | A few months, with no way to extend |
| Layout | A whole cage or a block of cabinets side by side | Scattered single cabinets |
| Network | Many carriers and cloud on-ramps in the building | One or two carriers |
| Ready date | Empty and ready now | Still full of equipment that has to come out first |
We work with buyers who are looking for space. When your space fits a current requirement, it can move faster than a public listing. See available capacity for the kinds of space buyers are matched with now.
Subleasing a GPU contract
The same problem shows up with GPU cloud contracts. A company reserves a GPU cluster for 12 to 36 months. Then the project changes and the GPUs sit idle. The bill does not change.
We place those too. A sublease or transfer moves the unused GPUs to a company that needs them for the rest of the term. The provider has to agree, just as a colocation operator does. GPU contracts are often easier to place than space. The big clouds sell GPUs on one-year and three-year terms, so a few months of B200 or B300 capacity is hard to find.
Send the GPU model, count, months left and provider in the form below. For the full detail on GPU contracts, see subleasing a GPU contract at GPU Rentals, our GPU site.
What to send us
You do not need all of this to start. The more you have, the faster we can tell you what is possible.
- The operator and the market
- What you want to place: cabinets, a cage, a suite or committed power
- Committed kW and the power per cabinet
- Your monthly charge and the date the term ends
- Whether you want out of all of it or only part
- When the space can be empty
- For a GPU contract: the provider, GPU model, GPU count, rate and months left
Colocation sublease FAQ
Can I sublease colocation space?
Usually, with the operator's written consent. Most colocation agreements let the operator approve or refuse a sublease or assignment. Some refuse when the subtenant would compete with them for the same customers. Check the consent clause in your agreement first. See what the operator has to approve.
What is the difference between a sublease and an assignment?
With a sublease you stay on the contract and the subtenant pays you. With an assignment the new company takes over the contract itself. An assignment can release you completely, but only if the operator agrees to release you.
Can I sublease part of my space?
Often, yes. A block of cabinets in one row, or a cage that can be split, is easier to place than scattered cabinets. Shared power and network gear may need to be separated first.
Will the operator just take the space back?
Sometimes. In a market with little open space, the operator may want the space back for a waiting customer. It may let you out for a fee, or for less than your remaining payments. We ask before we look for a subtenant.
Can I sublease a GPU cloud contract the same way?
Usually, if the provider agrees. The unused GPUs move to another company for the rest of the term. See subleasing a GPU contract.
