Typically situated in large metropolitan areas where demand for content and applications is high, these carrier neutral data centers cater to a range of companies. Networking companies, e-commerce and content providers, financial exchanges, cloud service providers (CSPs), software as a service (SaaS) providers, and enterprises all use these facilities to establish points of presence (PoPs). At these PoPs, they place networking equipment, servers, and storage devices to create digital ecosystems.

The carrier neutrality of these data centers represents an unbiased telecommunications and network environment. Unaffiliated with any single telecommunications provider, they allow many carriers to extend their fiber optic networks into the facility, to offer services to the customers of the data center. This allows content and application companies to connect to essential telecommunications networks to reach enterprises and consumers.

Common alternate names for a carrier neutral data center include network neutral data center, carrier neutral facility, carrier hotel, interconnection hub, and peering hub.

Understanding Carrier-Specific Data Centers

Data centers are generally classified into two types: carrier-specific and carrier neutral.

Carrier-Specific Data CentersCarrier Neutral Data Centers
NetworkTypically bound to a single carrierOffers access to multiple carriers
FlexibilityLimited flexibility as services are tied to the specific carrierHigher flexibility in choosing and changing carriers
PricingPricing dependent on the carrier’s policy; may not be as competitiveCompetitive pricing due to the presence of multiple carriers
ReliabilityReliability is dependent on the single carrierIncreased reliability due to multiple carriers that can take over
LocationOften the only option in non-major citiesLarge metropolitan areas
OperatorsVerizon, AT&T, VodafoneEquinix, Digital Realty, CoreSite

Carrier-specific data centers are dependent on their own telecommunications network for connectivity. They are owned, operated, or significantly influenced by a single telecommunications company, such as Verizon, AT&T, Vodafone, or Telefónica. This arrangement limits customers to using only the services and connectivity options provided by that specific carrier.

In contrast, carrier neutral data centers, operated by companies such as Equinix, Digital Realty, and CoreSite, offer access to multiple carriers, providing more flexibility, reliability, and better pricing.

Customers at carrier-specific data centers often only have one or few options for connectivity services. This situation can lead to disadvantages such as high prices, sudden changes in service or pricing, limited bandwidth, and a lack of competitive options, as customers are dependent on the services of the provider to which the data center is affiliated.

Historically, network providers primarily relied on a limited number of carrier-specific data centers, known as network access points (NAPs), to exchange traffic with each other. Major telecommunications companies built these data centers mainly to sell bandwidth and to target customers with significant needs for managed services, as part of their pricing structures. However, these facilities have largely become obsolete.

Types of Carrier Neutral Data Centers

Carrier neutral data centers are operated by companies that are not telecommunications carriers themselves. Instead, they depend on third-party carriers to provide connectivity services to their customers. The range of carriers hosted in these carrier neutral data centers varies depending on the facility’s size and location:

  • Small or Regional Data Centers: These facilities typically accommodate between 2 and 10 carriers. They primarily feature major local or national providers such as Verizon, AT&T, Comcast, and Cox Communications in the United States
  • Large or Major Market Data Centers: Located in urban areas or at regional internet exchange points (IXPs), these data centers often host 10 to 100 carriers. They include a diverse mix of international, national, and regional providers. Notable examples are Lumen Technologies (formerly CenturyLink), Windstream, Zayo, British Telecom (BT), and NTT Communications
  • Top Tier Data Centers: As global internet hubs, these facilities host an extensive range of 100 to over 400 carriers, featuring global companies and service providers. In addition to the carriers mentioned above, these facilities often host carriers like Cogent Communications, Tata Communications, Vodafone, Telefónica, and China Telecom

Benefits of Carrier Neutral Data Centers

Carrier neutral data centers play a crucial role in the landscape of data management and internet infrastructure.

Here are six key benefits of using these facilities and why they are important:

1. Connectivity and Network Diversity

Carrier neutral data centers provide access to multiple telecommunications and network providers. This diversity allows customers to select carriers and internet service providers (ISPs) based on factors like price, service quality, and reliability, ensuring the best possible connectivity for their specific needs.

For example, these facilities host specialized connectivity providers, including those offering ultra-low-latency links between stock exchanges (such as NYSE or NASDAQ) and the computing equipment of high-frequency trading firms. Additionally, carrier neutral data centers serve as shared access points for connecting to subsea cables, like Trans-Atlantic systems, facilitating global data transmission.

Ultimately, the presence of leading network providers in these carrier neutral data centers attracts more companies, creating a network effect. Businesses gravitate towards facilities used by their partners to reduce costs and improve operating efficiency.

Case Study – Equinix’s Ashburn Campus

A prime example of this ecosystem is Equinix’s data center campus in Ashburn, Virginia. Starting as a single building with 400 cabinets and less than 1 megawatt of power capacity in September 1999, it has expanded to 15 data centers, featuring over 32,000 cabinets, 111 megawatts of power capacity, and more than 38,000 interconnections. In nearly 25 years, this growth has positioned Equinix’s Ashburn campus as a hub for carrier neutral data center services in Northern Virginia.

This network effect and ecosystem have led many enterprises to extend their corporate wide area networks (WANs) to these interconnected, carrier neutral environments. For instance, at Equinix’s Ashburn campus, customers can access network services from over 200 providers. This allows for seamless integration with a wide array of network, cloud, and IT service providers.

2. Cost-Effectiveness

Carrier neutral data centers deliver cost savings in multiple ways:

  • Reduced Bandwidth Costs: Carrier neutral data centers can lower networking costs related to bandwidth by approximately 25% to 40%, compared to carrier-specific facilities. This cost reduction is possible because of the competition among multiple carriers within the same facility, enabling customers to negotiate better pricing with various providers, given the presence of alternative providers in the same facility
  • Internet Exchange Points (IXPs): Carrier neutral data centers often host internet exchange points (IXPs), which can decrease transit costs by up to 50% through peering agreements
  • Cloud Services Access: Carrier neutral data centers typically offer more affordable access to major cloud service providers (CSPs), such as Amazon Web Services (AWS) and Microsoft Azure. They provide direct connectivity to these cloud providers through services like AWS Direct Connect and Azure ExpressRoute. This direct connection is not only more cost-effective than routing traffic over the public internet but also provides lower latency and ensures consistent uptime

3. Reliability and Redundancy

Carrier neutral data centers host multiple carriers, enabling businesses to establish redundant network connections under stringent service level agreements (SLAs). This multiplicity of carriers enhances network reliability and substantially reduces the risk of downtime. Redundancy is primarily achieved through cross connects – physical cable links that connect a customer’s network equipment to various carriers’ equipment.

For example, a business may house its server or networking hardware, such as switches and routers, in a rack within the data center. These devices are physically connected to the networks of multiple telecommunications carriers through cross connects, which can be fiber optic, copper, or coaxial cables. This connection typically takes place in a dedicated space known as a meet-me room (MMR), where the networking gear of different carriers and customers converge.

In the event of a service outage from one carrier, these setups are designed to reroute traffic to another carrier’s network seamlessly. As a result, customers using carrier neutral data centers benefit from higher availability, striving for 99.999% uptime, since they are not reliant on a single carrier and can maintain connectivity as long as alternative carriers are operational.

4. Network Performance

Carrier neutral data centers improve network performance by offering access to an extensive array of telecommunication carriers, internet service providers (ISPs), content delivery networks (CDNs), cloud service providers (CSPs), and application service providers. This wide selection allows customers to choose the fastest and most efficient networking routes for their data, leading to optimized information flow.

These data centers feature multiple points of presence (POPs), serving as gateways to the internet. POPs facilitate connections to a wide range of network points, such as those operated by telecommunications companies (carrier POPs), local telecom buildings (Central Offices, or COs), and mobile phone communication facilities (mobile switching centers, or MSCs). This abundance of connection options allows carrier neutral data centers to transmit and receive data more quickly and reliably, thereby enhancing network performance.

5. Reduced Latency

Carrier neutral data centers provide customers with “zero mile” access to robust connectivity, which refers to the facility’s direct and immediate connectivity to major internet backbone networks, without the need for local loop or long-haul fiber connections. By being directly connected to the primary networks that form the core of the internet, data can travel to and from the data center more quickly, reducing latency.

Carrier neutral data centers reduce latency through direct interconnections, commonly known as cross connects, between diverse networks. Such direct connections decrease the physical distance that data must traverse from its origin to its destination, resulting in reduced propagation delay. Consequently, this can reduce latency by up to 50% compared to internet-based routing, leading to quicker information exchange.

6. Flexibility and Scalability

Carrier neutral data centers allow businesses to easily scale their operations up or down. Companies can switch carriers, increase bandwidth, rent additional colocation space, establish new interconnections, or employ new services without relocating their IT infrastructure or changing data center locations.

Additionally, carrier neutral data centers provide access to other data centers and services across many metropolitan areas worldwide. This accessibility enables businesses to deploy and scale network components, connectivity, and services more effectively and closer to their customers’ users and resources.

For instance, Equinix, the world’s largest colocation provider, operates 251 carrier neutral data centers in 70 metropolitan areas across 32 countries. Many of these facilities are interconnected by Equinix Fabric, a software-defined interconnection service. This service allows businesses to connect globally with a wide array of networking, storage, compute, and application service providers using virtual connection speeds of up to 10 Gbps.

Services Offered by Carrier Neutral Data Centers

Carrier neutral data centers, which offer a range of services to customers from various carriers or network providers, typically deliver the following common services:

These services connect disparate physical or logical networks, enhancing business connectivity. They facilitate access to network services, enable traffic exchange, and allow for easy switching between providers or adding new ones. For instance, customers can utilize interconnection services for IP transit, which is crucial for accessing the broader Internet. They also enable financial transactions, settlement functions, and business-to-business e-commerce.

Interconnection services at carrier neutral data centers offer two main options for network traffic exchange:

  1. Direct Connections: Customers can directly create one-to-one connections with service provider networks using the data center’s cross connect services
  2. Peering Connections: Customers can engage in peering with multiple parties by connecting to a shared platform at an internet exchange point (IXP), usually housed in a carrier neutral facility

Peering Services

Peering services, a specialized form of interconnection, involve mutually beneficial traffic exchange between network operators, usually without financial compensation. This arrangement enhances efficiency and mitigates the costs, delays, and performance issues associated with routing traffic through third-party transport services.

There are two primary peering types in carrier neutral data centers:

  1. Public Peering: Conducted at an internet exchange point (IXP), it involves multiple networks connecting to a shared peering platform to exchange traffic. Public peering is suitable for smaller volumes of traffic and generally comes at a lower cost
  2. Private Peering: This is a direct, exclusive connection between two networks, facilitated by a cross connect, bypassing a shared, public IXP platform. Private peering is ideal for larger volumes of traffic because it enables faster and more secure data exchange

Using these cloud on-ramps results in lower latency, higher throughput, and more consistent network performance. The dedicated connections enhance security as data is less exposed to the vulnerabilities of the public internet. Furthermore, cloud on-ramps can reduce data transfer costs, particularly for large volumes of data.

Carrier neutral data centers hosting cloud on-ramps enable businesses to efficiently operate hybrid and multi-cloud deployments. They allow seamless integration of on-premises infrastructure with multiple cloud services.

For instance, the following map demonstrates how Equinix, the world’s largest carrier neutral data center provider, hosts two or more major cloud on-ramps in almost all of its top 50 data center markets globally:

In total, Equinix has more than 210 cloud on-ramps worldwide. Notably, in 25 markets, Equinix hosts the top three cloud service providers simultaneously, and in 12 markets, it hosts five or more of the major cloud service providers concurrently.

Managed Services

Managed services in carrier neutral data centers comprise a variety of IT solutions, including server management, storage management, and network management, as well as disaster recovery and backup services. The main goal of these managed services is to reduce the burden on a customer’s IT staff. This allows the IT staff to concentrate on strategic business goals and managing applications, rather than on maintaining the data center’s infrastructure.

While carrier neutral facilities typically employ their own personnel for basic services like remote hands (e.g., cable management and basic equipment troubleshooting), they often collaborate with third-party vendors for more specialized or technically demanding tasks. These tasks include smart hands services, such as equipment configuration and installations.
