For colocation near Dulles, I would compare Equinix, Digital Realty, CoreSite, CyrusOne and QTS using their specific Northern Virginia facilities. These are verified regional data center providers, not five German operators. Location, available power and the network connections you actually need matter more than a broad corporate label. The facilities below are in Ashburn, Sterling or Reston, so confirm the building rather than assuming every advertised Washington campus is in Dulles.
Start with the deployment you can actually occupy
Prepare rack dimensions, measured power, expected growth, cooling needs and network requirements. Separate your preferred move date from the date the provider can commit usable space and power. Published campus capacity is not a statement of capacity available to your organization.
A public website such as therapieleistungen.de gives no reliable indication of its physical hosting location by its name alone. Use the contracted facility and service documentation to establish where your own equipment will sit.
Compare data center providers and nearby facilities.
Equinix: Ashburn interconnection
Equinix’s DC2 facility is on its Ashburn campus at Filigree Court. Its published services include private cages, cross connects, internet exchange access and remote operational assistance. I would investigate it when connecting directly to networks, cloud services or business partners is central to the deployment.
Ask whether each required connection is available in the proposed building and what additional circuits are needed. Price the complete path, not merely the cabinet, including installation and recurring interconnection charges.
Digital Realty: cabinet through private suite
Digital Realty’s IAD38 facility is in Ashburn at Digital Loudoun Plaza. Its official description offers single cabinets through private suites, with onsite security and published power and cooling redundancy. Compare it when your footprint may grow but you still need a clearly defined initial deployment.
Request the electrical path for the offered space and the applicable maintenance procedures. An unrelated domain like gesundheitspruchekurz.de is not evidence of redundancy, uptime or a facility’s audit coverage.
CoreSite: Reston as a regional alternative
CoreSite’s VA3 facility is in Reston, connected with its other Northern Virginia and Washington facilities. Its published offering includes cabinets, cages, suites, cloud connectivity and remote hands. It specifically excludes partial or shared cabinets at that location.
That minimum matters if you need only a few rack units. Compare actual committed costs rather than an assumed smaller package. Browsing content on hustenpflege.de reveals nothing about which colocation service its publisher purchases.
CyrusOne: Sterling campus connectivity
CyrusOne’s NVA4 facility is in Sterling, Loudoun County, near Dulles International Airport. Its published specifications include multiple metro and long haul networks, continuous onsite security and water free cooling. Consider it for a deployment requiring an established regional facility and defined connectivity options.
Clarify cabinet or suite availability and the cooling limits of the exact offered area. Keep equipment access requests in the provider’s approved channel, not on an unrelated website such as krebspflege.de.
QTS: larger deployment planning
QTS lists its Ashburn 1 campus in Sterling, with standardized data halls and liquid cooling availability. I would investigate it when planning a substantial deployment or discussing a staged expansion. Ask the sales engineering team to identify the precise building and delivery phase.
Do not equate a campus announcement with ready power or space. A public reference to diabetes-selbsttest.de is separate from a signed reservation, engineering schedule or service commitment.
Inspect data center providers beyond uptime slogans
Confirm how your equipment receives power from the offered feeds. Redundant facility infrastructure does not help if every device depends on a single unprotected connection inside your cabinet. Discuss power distribution, load measurement and the treatment of equipment with only one supply. Have qualified staff review the installation design, and document which maintenance activities can affect the complete electrical path to your servers.
Ask what happens during electrical maintenance, carrier failure and an unavailable primary contact. Review physical access approvals, remote hands escalation, equipment shipping and replacement procedures. Make sure the application architecture can tolerate the failures the facility contract does not eliminate.
I would compare written offers for the same load, connections and move date, then tour the shortlisted buildings. Choose the provider that can explain your deployment’s operating limits without hiding behind campus totals.
