The data centers offer complete redundancy in power, HVAC, network connectivity, and security. The datacenter facilities sit atop multiple power grids, with full UPS battery backup power and a diesel generators onsite. Our network is supplied by several separate networks including, Level(3), NTT, GTT, and Tata.

Our data center facilities have been built to meet the high demands and reliability of telecommunications providers and Fortune 500 companies. They all maintain at least N+1 mechanical redundancy and 2N network redundancy. The fiber provided to the data centers is also provided over redundant paths, with diverse entry points and building riser. We also assure carrier neutrality at all of our facilities and can provide access to dozens of third party backbone providers from each of our buildings via cross connects.

We are always happy to give tours of all of our facilities. Simply contact us to schedule a tour.

The Facilities

350 E Cermak Rd Chicago Data Center

350 E Cermak Road, Chicago, IL (chi01-chi02)

350 E Cermak is our original data center facility and we have multiple phases with ones completed in each 2001, 2005, 2009, and 2011. It is the largest data center in the world (1.1 million sq. ft.) and the primary carrier hotel in Chicago with direct access, through Equinix and the building meet-me-room (MMR), to hundreds of networks, such as Verizon, Zayo, CenturyLink, XO Communication, Sprint, AT&T, and Cogent. Ideal for those in need of diverse connectivity or for trading/financial purposes due to the proximity to the Chicago Mercantile Exchange (CME) and the Intercontinental Exchange (ICE) in addition to many other financial networks and exchanges.

725 S Wells Chicago Data Center

725 S Wells Street, Chicago, IL (chi18)

Our newest facility, completed in 2010 with planned expansion for late 2013. It offers direct connectivity (over 400 Gbit/sec of redundant capacity) to 350 E Cermak Rd along with a building MMR consisting of Zayo, Cogent, Sidera, Verizon, CenturyLink, and others. As a whole, the facility offers strong connectivity options in a downtown location for those needing a lower price point than is possible out of 350 E Cermak Rd.

121 Varick New York Data Center

121 Varick Street, Manhattan, NY (nyc16)

A new facility completed in early 2010, this facility offers easy connectivity to New York's premier carrier hotels, including 111 8th and 60 Hudson. Since the facility itself is not in a primary carrier hotel the pricing is some of the best in Manhattan, but still has numerous connectivity options.

Data Center Features

Fire Suppression System

A state-of-the-art fire suppression system constantly monitors the physical environment for smoke, chemicals and other hazardous materials that might spark a fire. The data center uses a dual-interlock pre-action sprinkler system throughout the facility. These pipes are dry-filled with compressed air - until two alarm conditions are reached thereby releasing the valve to charge the system. Water is only released in the area when a sprinkler head has lost its seal, or is actuated, due to heat, and the fire detection system has detected a fire condition. If a head is accidentally knocked off, water does not flow into the system. Any water discharged will be sprinkler-head specific, which will limit the potential for damage caused by over-spray.

Redundant and Precise HVAC System

Air control is critical in maintaining fast, efficient performance from our customers' equipment. To create the right environment, the data center is fitted with a comprehensive HVAC system that delivers constant, ideal air conditions, between 68 and 74 degrees Fahrenheit and between 40% and 50% relative humidity at all times. Our HVAC system uses efficient and effective chilled water cooling, not a standard forced/chilled air configuration. HVAC systems maintain a minimum of N+1 redundancy, allowing the data center to maintain a constant, cool environment that is conducive to our customers' mission-critical equipment and operations.

Redundant Power and UPS

The power systems are equipped with a level of redundancy that guarantees continuous operation. To ensure that the data center is always operational all the time, a multi-layer power generation system, using some of the highest grade equipment available, is in place. Conditioned AC power with two independent A & B power buses, respectively, is available. In addition, UPS, battery and diesel generators back up every power system. Unlike some other data centers the climate control and security measures are also backed up with redundant power to ensure clean operation during power outages. The UPS systems maintain at least 15 minutes of battery backup and onsite diesel generators are brought up automatically within seconds for longer outages.


All of our facilities have completed SSAE16 audits to help assure proper methods and procedures to assure optimal security compliance. Visual confirmation and strict sign-in procedures, both conducted by trained security personnel, along with key cards, and photo ID verification ensure that only authorized personnel have access to our data center. No customers are allowed in our space unattended and staff is on-site 24/7. In addition, all aspects of the data center are monitored and recorded via color, hi-resolution digital video cameras. All logs and video footage are kept on hand for a period of at least 90 days.
