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.

Green House Data (Multiple)

Greenhouse is very well situated with over 250 carrier connections. Being in the Westin Building Exchange offers them great access to global and asian networks. 

Our take. Greenhouse comes across as an enterprise cloud provider built on VMWare. They are HIPAA compliant and offer 3 locations for colocation across the country.

NYI Seattle

NYI in Seattle is robust and uses 98% renewable energy to power its 25,000 SQ FT facility. 

Our Take: We like NYI's diverse offerings. They have excellent facilities and have cloud and managed offerings as well. 

3101 Western Avenue, Level C, Seattle, WA 98121 (more info)




TierPoint's 20k square foot facility in Seattle has many certifications if you need SOC 2 or HIPAA compliant facilities. 

Our Take: TierPoint can certainly handle all your colocation needs with their very redundant power, network and cooling infrastructure. As we've mentioned in our other city guides for colocation, you can expand into their managed or cloud offerings since they offer those as well. 

140 4th Avenue N, Suite 360, Seattle, WA 98109 (more info)



Another Westin building colocation facility that offers 50 connectivity options. 

Our Take. While not a huge facility it's strategically located and can give you great access to various network carriers. There's also an interesting Metro interconnect product that can allow downtown Seattle offices to be on the same network as their colocation facility. 

2001 6th Avenue, Seattle, WA 98168 (more info) There is also a downloadable spec sheet


Sabey Data Center Properties (Multiple)

Sabey Datacenter’s are similar in nature to H5 datacenter as they serve larger enterprises and service providers as they offer powered shells and wholesale colocation only.

Our Take. If you are a large company, colocating in a custom (turnkey) shell allows you to pay for your exact power usage and to leverage economies of scale you may have with insurance and equipment. Generally, your costs will be much better than retail colocation but there are minimum amounts of square footage you can lease.

3333 S 120th St, Seattle, WA (more info)


Equinix (Multiple)

Equinix is most known for its amazing carrier connections and peering inside the data center. Businesses that require massive interconnections between various networks rely on Equinix to give them solid access. Major public cloud providers also are available through direct connections.

Our take. You are buying some of the best interconnected and mission critical colocation on the planet. They will certainly not be the cheapest of prices but you will get a solid value.
