Atlanta-based DC Blox scored $37 million in Series B funding that it will use to build three new data centers across the Southeast in support of multi-access edge computing (MEC) and cloud services. The firm has raised more than $53 million in total funding since its launch in mid-2016.

The new data centers will be in Birmingham, Alabama; Greensboro/Winston-Salem, North Carolina; and Greenville, South Carolina. The company has data centers up and running in Atlanta and Chattanooga, Tennessee, and a data center under construction in Huntsville, Alabama.

Two of the new data centers are expected to be completed by year-end, adding at least three megawatts of power to its total operations. The data centers are connected using a Ciena-provided fiber optic network capable of carrying data at 8.8 Tb/s. That network includes Ciena’s 6500 and 8700 converged packet optical and packet networking platforms.

Customers can tap into the data centers at connection speeds up to 100 Gb/s. The firm focuses on Tier-3 markets that are typically underserved by larger data center providers.

“This latest round of funding reflects the confidence our investors have in our strategy to deploy edge data centers in underserved markets that support the needs of enterprise businesses, government entities, content providers, and managed service providers in the Southeastern United States,” said DC Blox CEO Jeff Uphues in a statement.

A recent report from 451 Research noted that DC Blox was starting to look at expanding into larger markets and disaster recovery services in an effort to boost growth.

“DC Blox’s original strategy of going after small secondary markets was certainly interesting, but admittedly would have taken a while to realize the company’s goals. Small markets just don’t move fast,” the report stated. “On the other hand, deciding to focus on large markets while leveraging these edge markets for backup/[disaster recovery] seems like a solid plan, and will likely get off the ground a little quicker.”
