Reviews of the Best Data Center Providers in Ashburn, Virginia

What if I told you that most of the data you're churning out on a daily basis goes through a rural county that is most well known for pastures, farms and scenic views of the Blue Ridge Mountains?

Because of happenstance, prudent public policy, the proximity of the federal government and a little bit of luck, Northern Virginia and Ashburn, in particular, has become home to many of the Internet's leading data center companies.

But, with so many good options available, choosing a data center provider in Ashburn, Virginia, requires due diligence. Considering the critical role of data and the increased adoption of cloud computing, small to mid-sized enterprises would do well to evaluate data centers beyond their hardware and software capabilities. A data center’s site location is equally important.

Northern Virginia has become one of the world's leading hubs for data centers, but before you can determine which is right for your business, you need to understand how important data center selection is.

The Best Data Center Providers in Ashburn, Virginia

To find the best data center providers in Ashburn, it pays to do your homework.

Some organizations prefer to employ a set of site-selection criteria with emphasis on cost and availability of both power infrastructure and WAN (wide area network). Others tend to prioritize socio-economic, environmental, and governmental factors.

Whatever your site-selection criteria for selecting data centers, we’ve outlined an overview of your data center options in Ashburn so you can determine which is best for you.

But before we dive into the options, understanding the benefits of selecting a Northern Virginia data center could offer additional insights to help with your decision.


Why Data Center Buyers and Suppliers Are Choosing Ashburn

Half of the Northern Virginia data center market is in Ashburn, with the surrounding area in Loudon County covering the other half. The data center space in Ashburn covers over 9 million square feet (840,000 sq. mi.), with two-thirds already fully operational and the remaining third currently under construction.

Enterprises in the market for colocation space are quick to choose Ashburn because the area has controlled access to a large part of the Internet as a whole since it hosted the MAE-East exchange over twenty years ago.

On top of that, Ashburn offers tax incentives, competitive power costs, and has more available land than Silicon Valley and the New York/New Jersey areas. In fact, data center incentives are best-in-class in the region with a five percent tax exemption on servers, chillers, generators, and server-related equipment. Additionally, you don't have the threat of earthquakes as there are in California or the hyper-density of the NY/NJ region.

So, without further adieu, the best data center providers in Ashburn, VA.

Atlantech Online's growing network provides fiber connectivity to businesses in Ashburn, but our data centers actually sit just outside the area, in both Rockville and Silver Spring, Maryland. While our actual data centers are not technically in Ashburn, they are connected to Ashburn because of the metro area rings of Atlantech's fiber network.

Both data centers are connected directly to a multi-substation power grid with online battery and diesel generator backups and with contracts to fuel providers to run indefinitely. For this reason, our clients enjoy low latency peering relationships direct to their data center with high-speed, high-bandwidth fiber connectivity.

We also provide our own internet business-class phone service solutions. Think of us as a 'one-stop' source for your business communication needs.

Thanks to Atlantech, when your phone and internet service provider is also your data center solution, business operations run more efficiently and smoothly.
