    Carrier Hotels: An Inside Look

    In the interconnected world of the 21st century, the invisible networks that keep us connected to the web are often taken for granted. As we send emails, stream movies, and engage in video calls, we seldom pause to ponder the complex infrastructure that makes this possible. At the heart of these networks lie the unsung heroes of our digital age: The carrier hotel.

    These are not your typical hotels. There is no concierge or room service here. Instead, they are bustling hubs of data exchange that house the servers, routers, and fiber-optic cables which form the backbone of the internet. 

    In this blog post, we’ll pull back the curtain on these fascinating facilities, offering an in-depth exploration of their role, functioning, and pivotal role they play in our global communications network. Whether you’re a tech enthusiast or a curious layperson, buckle up for an enlightening journey into the nerve centers of our digital world!

    What is a Carrier Hotel?

    A carrier hotel, also known as a telecom or carrier-neutral data center, is a physical location allowing different telecommunications and data companies to centralize their operations. These massive buildings serve as an anchor points for high-speed fiber-optic cables and other networking equipment. They act as meeting points for networks. Internet Service Providers (ISPs), telecommunications companies, and content delivery networks can interconnect their hardware directly, bypassing the need for a third-party intermediary.

    You’ll find rows of servers, switches, and routing equipment within their walls, all humming away in climate-controlled rooms. These servers store, process, and transfer the data we send and receive over the internet.

    The network connectivity provided by carrier hotels is their critical function. These connections, known as peering arrangements, are vital. They allow data to flow from one network to another, connecting users to websites, services, and each other. Carrier hotels enable more efficient data exchange, faster speeds, and greater resilience against network failures by providing a place for these networks to interconnect.

    Despite their low profile, carrier hotels are instrumental in the smooth functioning of the internet. They are the backbone of our digital world, ensuring our messages, calls, social media posts, and streaming videos reach their intended destinations quickly and reliably. 

    How Do Carrier Hotels Work?

    Carrier hotels function as centralized hubs where different networks can interconnect directly, leading to more efficient and faster data transfers. Here’s a step-by-step rundown of how these facilities operate:

    Housing Infrastructure

    Carrier hotels are built to house the physical infrastructure of various internet and telecommunications companies. This includes servers, routers, switches, and high-speed fiber-optic cables that carry data across the internet. Companies rent space in these facilities to install their own equipment.

    Interconnecting Networks

    Once the physical infrastructure is in place, networks can establish connections. This is done through a process known as “peering.” Peering involves the mutual exchange of data between different networks without a cost. It’s like an agreement between networks to allow data to flow freely, improving the speed and efficiency of data transfer.

    Data Transfer

    When you send an email, stream a video, or browse a website, the data travels through these interconnected networks. For example, if you’re in New York and want to access a website hosted on a server in London, the data might pass through multiple networks within a carrier hotel to reach its destination.

    Scalability and Adaptability

    Carrier hotels provide a flexible environment where companies can quickly scale their operations up or down. If a company needs more space, power, or cooling for its servers, it can adjust its setup within the carrier hotel to meet these needs.

    Security and Maintenance

    Carrier hotels provide 24/7 security and technical support to protect and maintain critical infrastructure. This includes physical security measures like surveillance and access controls, as well as digital security measures like firewalls and DDoS protection. They also ensure the environment is suitable for the equipment, with climate control, fire suppression systems, and backup power supplies.


    Redundancy is a crucial feature of carrier hotels. They typically have multiple power sources and internet connections to ensure that others can take over if one fails. This is crucial for maintaining the uninterrupted data flow and running the internet, even during unexpected events or failures.

    In essence, carrier hotels are the physical embodiment of the internet’s interconnectivity, facilitating the smooth flow of data across the globe. They are a testament to the complex behind-the-scenes operations that connect us daily.

    The Biggest Carrier Hotels in the United States

    There are carrier hotels sprawled across different American cities from New York to California. We have outlined five of the most prominent ones below.  

    Carrier Hotel City and State Major Colocation Service Provider 
    60 Hudson Street New York City, New York. Digital Reality
    624 South Grand AvenueLos Angeles, California. CoreSite 
    350 East Cermak RoadChicago, Illinois. Equinix
    50 NE 9th Street Miami, Florida. Equinix 
    1950 North Stemmons FreewayDallas, TexasEquinix

    60 Hudson Street 

    The carrier hotel at 60 Hudson Street in New York City was constructed in 1930 to be a Western Union telegraph office. However, it was renovated in 2013 to meet the demands of new technology. Today, the art deco-style building is 1.1 million square feet large, 24 stories tall, and takes up a whole city block. 

    Owned and managed by the Stahl Organization, 60 Hudson Street is home to hundreds of telecommunication companies and SaaS providers. The carrier hotel also houses data center operators who lease their spaces to businesses needing colocation services in the Empire State

    624 South Grand Avenue

    The 30-story carrier hotel at 624 South Grand Avenue is in Los Angeles’s core. Popularly known as One Wilshire, the carrier hotel is 661,553 square feet large. It was built in 1967 but was refitted in 1992 to house telecommunications and colocation infrastructure

    One Wilshire accommodates more than 300 network service providers and can access several satellite earth stations, making it a vital to Los Angeles’ colocation industry. Almost all the big data centers in the city connect to One Wilshire. 

    624 South Grand Avenue is also well known in the data center space for its connection to several undersea fiber optic cables. These cables provide connection from America’s West Coast to the Asia-Pacific region. 

    350 East Cermak Road

    The carrier hotel at 350 East Cermak Road is about 1.13 million square feet large and eight stories tall. Sitting in downtown Chicago’s main section, 350 East Cermak Road used to be a popular printing plant before its renovation in 1999 – 2000. 

    Equinix alone serves almost 200 network service providers at 350 East Cermak Road and leases about 133,500 square feet of data center space. However, Digital Reality, another major colocation service provider, owns the carrier hotel. 350 East Cermak Road’s location in Chicago’s core is one of the main factors that make it a great option for colocation in the Midwest

    NAP of the Americas – 50 NE 9th Street 

    The carrier hotel at 50 NE 9th Street in Miami is called NAP of the Americas. It is a six-story, 750,000 square-feet building that was built in 2001 for data center purposes. 

    Located in the heart of Miami, NAP of the Americas is strategically placed to control network traffic between the US and Latin America, and the Caribbean. The area has abundant interconnection infrastructure, such as undersea cable landings and fiber optics loops. This enables the carrier hotel to connect multiple countries effectively.  

    NAP of the Americas also offers access to exchanges like the Florida Internet Exchange and the Miami Internet Exchange. However, the carrier hotel is most popular for connecting to other parts of the Americas from Miami.

    Infomart – 1950 North Stemmons Freeway

    Infomart, the carrier hotel at 1950 North Stemmons Freeway in Dallas, is about 1.58 million square feet large and seven stories tall. Infomart was built in 1985 and has undergone several renovations to adapt to modern technology.  Equinix owns and manages much of the colocation space at Infomart, providing interconnection to more than 140 network service providers. 

    Infomart is the busiest Dallas colocation hub, and like NAP of the Americas, it also provides traffic to Latin America. So, it’s an excellent option for businesses looking to expand their reach or already have enterprises in the area.
