American Tower Internet Exchange at Our Facilities

The American Tower Internet Exchange offers neutral internet exchange services for all categories of internet service providers, content service providers, cloud service providers, academic networks, government networks, and enterprise networks in the Southeastern U.S. that desire a neutral-peering point.

Formed in response to industry demand for advanced IX global peering technologies, our internet exchange offers 100 Mbps to 10 Gbps access ports and both IPv4 and IPv6 peering. Route servers will allow networks to simplify their peering operations, while our internet exchange will permit other traditional peering models, utilizing either user-managed peering or VLANs to meet member objectives.
