Ten Most Connected Data Centers

Data centers are perennially difficult to rank, due mostly to the fact that different data center users place different amounts of value on each server farm characteristic. Electrical and mechanical infrastructure redundancy may be more valuable to a bank than to a cloud startup, for example, while a big cloud provider may emphasize the site’s capacity for expansion.

The one characteristic that’s emerged as paramount in recent years is data center connectivity. More precisely, the variety of connectivity options available at a site. As companies increasingly have to deliver digital services at global scale, having access to as many network providers as possible that will help them do that is more important than ever.

Data center connectivity is one of the ways a new online directory, launched by the Australian internet entrepreneur Bevan Slattery, ranks the world’s data centers. Slattery’s company Megaport, whose software platform automates the process of connecting to various service providers in a data center, went public in Australia last December. He co-founded a telco called Pipe Networks and founded NextDC, one of Australia’s biggest data center providers, which went public in 2010.

His new company, called Cloudscene, wants to bring clarity to the convoluted data center market by creating a directory of some 4,700 data centers and 4,200 cloud and internet service providers across 110 countries. In a statement, Slattery said he was frustrated with “the traditionally long and difficult buying process for data centers and enterprise cloud services.”

“Prospective tenants or home buyers haven’t needed to visit individual websites of real estate agents to get listing information for over a decade,” he said. “So, why is the tech industry stuck in the past when it comes to enterprise IT services?”

There is at least one other website that aims to be a comprehensive listing of the world’s data centers (http://www.datacentermap.com/), but it doesn’t rank sites by data center connectivity, service providers, network fabrics, and markets the way Cloudscene does.

Here are the top 10 most connected data centers, according to Cloudscene:

    In about 7 seconds I can think of three buildings in the US with more service providers than SG1, in about 7 more I could come up with three more.

  2. Pieter van Veen

    I find it odd that not a single Amsterdam datacenter is in this top 10 when AMS-IX is the 2nd largest Internet Exchange in the world with about 700 organizations & Service Providers connecting to it. And likewise no Frankfurt datacenter while DE-CIX is the largest Internet Exchange in the world.

    Good question Pieter. Do all companies peering at internet exchanges also provide services in those exchange locations? P.S. Equinix's FR5 in Frankfurt is on the list

  4. Yevgeniy Sverdlik Post author

    Thanks for your comment Jack. Could you specify which buildings please? Could the reason be that they listed facilities by specific operators that don't necessarily take up entire buildings?

  5. This top 10 and these numbers are far from correct. The truth is that it's very difficult to know exactly which networks or which fibers/cables are where. Regarding connected networks in terms of IP networks you can look at peering resources like the Peering DB or you can look at the number of connected networks that a IX (Like AMS-IX or NL-IX) has per location. That won't give you an exact number but a good indication. This data is published openly on the web. Regarding Amsterdam, as the Digital Gateway to Europe, Equinix AM7 should be high on this list with 194 networks according to AMS-IX. SARA, Nikhef, Global Switch, Equinix AM5, Digital Realty AM1 and EvoSwitch AMS1 are also highly connected in the Amsterdam area according to the Peering DB. Hope the incorrect data in this article can be corrected.
