These four names refer to different things: Terremark was an IT and data-center provider acquired by Verizon in 2011; APC is Schneider Electric’s backup-power and IT-infrastructure brand; DataBank is a current colocation and enterprise infrastructure provider; and the Involta website now presents its business as Ark. For readers comparing infrastructure options, the key distinction is that APC sells physical power-protection products, while DataBank and Ark describe data-center and related services.
How the four names compare
| Name | What it is | Status supported by the available company or public records |
|---|---|---|
| Terremark | Historical managed IT infrastructure and data-center provider | Verizon completed its acquisition in April 2011; the current successor or operator of former Terremark assets is not established by the sources cited here. |
| APC | Schneider Electric brand for backup power and physical IT infrastructure | A product brand, not a colocation operator. |
| DataBank | Colocation, cloud, networking, and data-protection services | Currently describes an enterprise infrastructure platform and reports a footprint of 70+ data centers in 25+ U.S. metro markets. |
| Involta / Ark | Enterprise infrastructure services, including colocation, private cloud, and networking | The Involta-domain site currently presents the business as Ark and describes owned-and-operated data centers. |
What happened to Terremark?
Terremark was a managed IT infrastructure provider and data-center operator. Its historical offerings included colocation, managed hosting, network services, disaster recovery, security, and cloud computing, as described in its fiscal 2008 SEC filing. At that time, Terremark reported more than 160 carriers in its facilities; that is a historical company figure, not a current count. Terremark’s fiscal 2008 Form 10-K
Verizon announced that it completed its acquisition of Terremark in April 2011 and that Terremark would become a wholly owned subsidiary. The cited public record establishes the acquisition, but not who operates the former facilities today or what successor brand, if any, applies to them.

What is APC in a data-center context?
APC, or American Power Conversion, is a Schneider Electric brand associated with backup power and physical IT infrastructure. It is not a company offering colocation in the sense of renting space, power, and connectivity in a data center. Schneider Electric’s brand history records its acquisition of APC in 2007 and the launch of APC Smart-UPS in 1990. Schneider Electric’s APC history
#1 Best Overall
For a business or individual looking for power protection, the relevant product path in this roundup is an APC Smart-UPS uninterruptible power supply (UPS). The cited history does not establish the specifications, capacity, runtime, pricing, or present availability of any particular model, so those details need to be checked against the product and equipment requirements in question.
What does DataBank do?
DataBank describes a current service platform spanning colocation, cloud, networking, and data protection. Its overview page reports 70+ data centers in 25+ U.S. metro markets. That is DataBank’s current company-reported figure on a page whose publication date is not stated, rather than an independently verified market count. DataBank overview

- Ideal for Gifting
- Ideal for a bookworm
- Compact for travelling
Its history records the acquisition of zColo data-center assets in December 2020 and the purchase of four Houston-area data centers from CyrusOne in January 2022. Those dated transactions explain parts of the company’s development; they should not be mistaken for a current facility count or a guarantee that a particular service is available at a given location.

Is Involta now Ark?
The current Involta website presents the business as Ark and describes enterprise data centers and infrastructure services, including colocation, private cloud, and network services. The site says the business was founded in 2007. Its wording identifies the current presentation on the Involta domain; it does not, by itself, establish every legal, ownership, or transition detail behind the Ark name. Ark / Involta about page

The company describes its data centers as owned and operated. For a potential customer, the location list and service details are more useful than the brand name alone: verify the specific facility, available power and density, connectivity, and the services offered there.

How to compare current infrastructure providers
DataBank and the business presented as Ark are the names in this roundup associated with current data-center and enterprise services. The sources cited here do not establish a head-to-head performance ranking, so compare the requirements of a specific deployment rather than assuming one provider is universally better.
Rank #4
- Geography and latency: Check whether a provider has a suitable facility near users, workloads, or existing systems.
- Power and cooling: Confirm the capacity and density available for the equipment you plan to deploy.
- Connectivity: Ask which carriers, networks, and interconnection options are available at the particular site.
- Service scope: Distinguish space and power from managed hosting, cloud, networking, or data-protection services.
- Security and compliance: Request evidence relevant to your organization’s requirements rather than relying on general service descriptions.
- Migration and contract terms: Clarify migration support, service levels, support coverage, and contractual commitments before selecting a facility.
Colocation and managed hosting are not the same service
Colocation generally means placing a customer’s own equipment in a provider’s data center, where the facility supplies infrastructure such as space, power, cooling, and connectivity. Managed hosting adds provider-managed IT services; the exact division of responsibility depends on the contract. Terremark historically offered both colocation and managed hosting, while DataBank and Ark currently describe broader infrastructure service portfolios. Ask each provider what its team operates and what remains the customer’s responsibility.
