CoreSite builds mission critical facilities which they offer for very competitive rates with good interconnectivity and many certifications. 

Our take. They excel at colocation and interconnectivity. Even with their robust build costs they don't appear to charge a premium for their space. CoreSite doesn't offer managed services directly.

PhoenixNap offers a robust colocation offering along with hardware leasing, managed network services and cloud backup / DR services that include Veeam. In our work with PhoenixNap we've found them highly responsive and competitive in their pricing. 

Our Take. A very strong data center provider with good access to other networks. Their managed DR and continuity offerings through Veeam are intriguing and should be examined for those seeking a DR solution.

Our take. You get much value for your IT spend with DRT. They offer flexibility in their power density which allows firms to save some money if they don't need high density computing environments. They feature excellent interconnection options and they have extremely robust power, network and support.

Flexential is the renamed entity of ViaWest recently merged with Peak10 . They offer colocation, HIPAA compliant cloud and a full suite of managed services. 

Our Take: The Flexential product suite is broad but with solid execution due to some strategic acquisitions. Flexential has long held excellent datacenter properties in top markets. Peak10 offered robust facilities in smaller US markets while ViaWest offered mission critical public and private cloud services with a specialization around HIPAA compliance.

QTS is known for their mission critical and large facilities. They offer colocation and a full suite of managed services that include cloud, disaster recover and traditional managed hosting services.

Our Take: We've worked with QTS in the past and the clients we've helped choose QTS don't regret it. Having the full suite of services also means that you can get out of the self managing business and have someone else completely take over their environment. Their past acquisition of Carpathia hosting gave them even more management capabilities than before.

Zayo has quickly grown their business with organic and acquisition growth. They have colocation in 30 markets globally and are well connected to the best networks. 

Our Take: Zayo not only offers mission critical colocation but they offer a robust portfolio of cloud and connectivity services. From cloud infrastructure to disaster service as a service they have it all under one roof.
