Carrier hotels, as data center buildings, facilitate the colocation of diverse networks, creating a crucial hub for seamless connectivity and information exchange. These dynamic ecosystems support high-speed data transmission, fostering collaboration between telecommunications carriers, internet service providers (ISPs), cloud platforms, content delivery networks (CDNs), large enterprises, and more.

A carrier hotel is an interconnected urban data center and central hub for networks and cloud services in major cities. Organizations co-locate equipment and connect to internet exchanges and cloud platforms, combining features of telecommunications facilities and data centers.

Dgtl Infra delves deeper into the world of carrier hotels, highlighting their importance and history while also presenting the top 25 carrier hotels in the United States. Keep reading to gain valuable insights into the role these critical hubs play in our increasingly interconnected digital society.

What is a Carrier Hotel?

A carrier hotel is a highly interconnected urban data center that serves as a central hub for networks and cloud services in major cities. Organizations can co-locate equipment and directly connect to internet exchanges and cloud platforms within the carrier hotel. Combining features of traditional telecommunications facilities and data centers, carrier hotels house multiple carriers in separate suites, with interconnection occurring via direct connections or through an intermediary meet-me room (MMR).

Importance of Carrier Hotels

Carrier hotels offer key benefits such as resiliency, redundancy, and the ability to choose between carriers, driving down network costs and improving performance. They also provide access to major public cloud service providers like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP), while enabling cost-effective cross-connects and traffic exchange via peering.

Meet-me rooms (MMRs) within carrier hotels reduce costs, lower latency (fewer network hops), and facilitate fast expansion by offering high-bandwidth, direct connections to multiple carriers. Furthermore, MMRs are secure, monitored spaces, ensuring minimal security breaches with multi-factor authentication and 24/7 surveillance.

History of Carrier Hotels

Carrier hotels emerged from the practice of connecting different telephone exchanges to facilitate efficient transfer of traffic between various network routes. Originally designed to accommodate the increasing number of long-distance carriers, these hotels have evolved in response to the shift from voice to data communications. They now serve to interconnect the backbones of various fiber optic networks. This evolution has eliminated the need to duplicate extensive long-haul copper and fiber optic cabling, as well as the replication of network equipment and devices.

Today, many carrier hotels are located in historic buildings, such as 350 East Cermak Road in Chicago and 111 8th Avenue in New York City, which have become interconnection hubs in their respective cities. Consequently, many carrier hotels have been retrofitted from their original design as office buildings to accommodate data center operations and meet the evolving needs of network interconnection.
