Colocation Service Providers

A colocation provider rents space, power, cooling, physical security and network connectivity in its data centers, so a business can run its own servers there instead of building and operating a facility. Customers usually own and manage the hardware, while the provider runs the building.

In colocation you bring your own hardware and the provider supplies the facility. In public cloud you rent virtualised capacity, and in bare metal as a service you rent dedicated servers owned by the provider. Many organisations mix colocation with cloud connections for hybrid IT.

Flexential is a US colocation provider. Its own materials describe a FlexAnywhere platform of about 40 data centers in 18 markets connected by a 100 Gbps+ backbone, with support for rack densities above 80 kW for AI workloads. One newer Flexential page cites 41 data centers in 19 markets, so confirm the current footprint with the company.

Compare locations and latency to your users, power capacity and cooling for the density you need, uptime commitments, connectivity and cloud on-ramps, security and compliance certifications, expansion room, pricing and contract terms, and how the provider supports remote hands and migration.

Yotta, CtrlS, Nxtra by Airtel, STT GDC India and Sify Data Centers. Check each provider for its current cities, capacity and certifications, and for data-residency requirements that apply to your workloads.

Links were checked on 4 November 2026. Descriptions follow each provider's own pages or company reports and are not independent rankings, and capacity and footprint figures change often. Several provider sites (Flexential, QTS, Switch, Vantage, TierPoint, STACK, EdgeConneX, Telehouse, Iron Mountain) block automated checks, so their links may need a manual click.
