Colo Atl Overview

Our History

Established in November 2001



Colo Atl was established in November 2001 by Tim Kiser in Atlanta, Georgia, one of the top colocation hubs in the United States. Focused on a “customer first” philosophy, Mr. Kiser envisioned a fully functional colocation facility and Meet-Me-Room (MMR) that would allow tenants to cross-connect – with no monthly recurring cross connect fees – within the space and offer a conduit for companies to network with other carriers within the facility.


In 2012, Colo Atl formed the Southeast Network Access Point (SNAP) in response to industry demand for advanced IX global peering technologies; and The Georgia Technology Center (GTC), a live laboratory for network equipment vendors to highlight their optical and electrical hardware and operating systems.


In 2015, Colo Atl expanded by an additional 6,400 square feet in response to the company’s growth and tenant demand.


In 2016, Colo Atl was named Best Colocation & Data Center – Georgia – by Technology Media Telecom (TMT) News. Colo Atl was selected for its dedication, hard work and focus on customer satisfaction.


In 2017, Colo Atl completed a 10,000-square-foot (sf) expansion on the fifth floor of its facility. 

The 10,000sf build-out offered tenants increased colocation and data center space, and many new amenities.


In 2019,  Colo Atl was acquired by American Tower, making it one of the earliest and most notable pairings between a data center company and wireless infrastructure company. The partnership provides Colo Atl customers with even more business opportunities by enabling greater possibilities for edge computing. 

Colo Atl has a 19+ year track record of continued growth and expansion with an unwavering commitment to excellence and a “customer first” philosophy.

As CallTower continues to expand in North America and internationally, Colo Atl was the absolute best colocation service option in the region of Atlanta for us. The company is reliable, responsible, and offers personalized customer service and attention to our needs. This level of customer service is superior to other competitors; the Colo Atl team will always pick up the phone to address our needs and questions.
Brandon Watts
Chief Technology Officer / CallTower
We needed to expand to an Atlanta point of presence (POP) to be able to optimize the route for our customers players who live near that region. Colo Atl was one of the only companies that was able to properly fit our needs in the area, and via our new location we are now handling traffic from Florida with lower latency and better reliability. It is extremely important that we had that set up regarding Anycast, GMCHosting’s custom stackable DDoS mitigation solution.

In meeting Tim Kiser, Owner and Founder of Colo Atl, we were immediately impressed with his knowledge and candid approach in helping HFT collocate in Atlanta. We thoroughly enjoy working through Tim and his team and leveraging Colo Atl’s key connections in the Atlanta area. Tim’s hands-on ‘I’m here to help’ mentality is what ultimately cinched the deal over other providers for HFT, being quite new to the Atlanta space.

In our search for a data center and connectivity service provider, it was imperative to find a vendor that could ensure business continuity, maximum bandwidth, security, and reliability for our customers’ websites and data reporting systems. We have found all of these qualities and more in Colo Atl and have received excellent service.

Our southeast low latency path to Colo Atl is the gateway to the south, and we selected this data center and interconnection facility for its prime location and the rich fiber carrier density it offers. Growing our direct peering with quite a lot of new peering sessions via Colo Atl is helping Pixel Factory to open up our southern path and lower our hops and latency into this region significantly.

Since becoming a tenant, Colo Atl has provided exceptional services without any issues. Everything has gone beautifully as planned, and when we required a few additional items we needed assistance with, such as Remote Hands service, Tim Kiser and team were more than happy to provide. Colo Atl is a carrier-neutral facility offering key interconnection opportunities and is very easy to work with, offering reliable service and incomparable management skills. If an opportunity presented itself for further expansion into Atlanta, Colo Atl would be our first choice.

Sharing colocation space with our sister company, ENT of Georgia North, we had great experience in housing our servers at Colo Atl’s secure facility in downtown Atlanta. When it came time for us to expand due to our growing patient roster and otolaryngology services, we already knew we had a trusted data center and interconnection services provider in Colo Atl, so the decision to expand our network within its facility was an easy one. Colo Atl is easy to work with, and offers reliable, secure colocation in an ideal location for us in Atlanta.

Our primary focus, of course, is our customers and ensuring utmost security for them as they do banking with us via one of our 27 locations, from home, or through a mobile device. As the banking industry continues to meet high technology demands, making our services available ‘anytime, anywhere,’ it’s imperative that we partner with the right technology providers to ensure these capabilities, securely and reliably. As Colo Atl was already connected to our top network providers, and considering its ideal location, choosing Colo Atl’s facility for data center and interconnection services was an easy choice. Since working with Tim Kiser and team, we’ve found the service and response time has been far superior to our other colo providers.
David Sheffield
Infrastructure Services Manager / Colony Bank
As a telecommunications and software services provider for the past 20 years, we have customers throughout the US, such as call centers, market research firms, polling companies and more who rely on our services for high volume long distance calling. We recently had a customer in the Atlanta area, and in response, BBD sought a data center interconnection provider in the area. In our search, we were fortunate to come upon Colo Atl and contacted its owner, Tim Kiser. After speaking with Tim, it was an easy decision to proceed. Colo Atl is a carrier-neutral facility offering key interconnection opportunities, and importantly, is extremely easy to work with, flexible and cost effective. Most importantly, Colo Atl took care of our immediate interconnection needs for our Atlanta-based customer.
