H5 Data Centers is a privately-owned U.S. colocation and wholesale data center operator headquartered in the Denver Tech Center, with facilities spanning roughly 25 markets across the country as of 2026. The company specializes in a mix of large wholesale colocation campuses (like its 452,300 sq ft Quincy, WA campus and 300,000 sq ft Denver campus) and downtown “carrier hotel” edge facilities that serve as major interconnection points for regional networks (Cleveland, San Antonio, Atlanta, New York). Founded by CEO Josh Simms, H5 has grown largely through acquisition — buying facilities from Yahoo, ByteGrid, NextFort, 365 Data Centers, vXchnge, and DivcoWest-owned buildings — rather than solely through ground-up development, though it has also built new facilities such as its 42MW Ashburn, VA campus. H5 markets itself as one of the largest privately-owned data center operators in the U.S. by square footage, offering turn-key colocation, private suites, cages, cabinets, and powered shells to enterprise, carrier, and cloud-services customers, but does not sell its own branded cloud compute service.

Common Questions
Does H5 Data Centers offer AI or GPU-optimized colocation?
There is no specific public evidence that H5 has built dedicated high-density AI/GPU colocation infrastructure; a 2026 report on its Cleveland facility explicitly noted the site does not host AI computing power, though an AI company was noted to be building network presence there rather than compute.
Where is H5 Data Centers headquartered?
H5 Data Centers is headquartered at 5350 South Valentia Way in the Denver Tech Center area (Denver/Greenwood Village/Englewood, Colorado), which is also the site of its 300,000 sq ft Denver colocation campus.
How many data centers does H5 Data Centers operate?
As of 2026, H5 Data Centers describes itself as operating around 30-36 data centers across roughly 21-25 U.S. markets, though exact counts vary slightly between the company's own site and third-party directories.
Is H5 Data Centers a wholesale or retail colocation provider?
H5 offers both: large wholesale suites and powered shells for hyperscale and enterprise tenants at campuses like Quincy, WA and Denver, alongside smaller retail colocation cabinets and cages at edge/carrier-hotel sites like Cleveland, San Antonio, and Atlanta.

Yes — H5's portfolio includes facilities acquired from Yahoo (Buffalo/Lockport and Omaha/La Vista), ByteGrid (Cleveland), NextFort (Phoenix), 365 Data Centers (Nashville and Buffalo carrier hotels), and vXchnge, in addition to ground-up developments such as its new Ashburn campus.
