About

What is MAINPORT?

MAINPORT is Frankfurt’s carrier-neutral connectivity fabric, directly present within Digital Realty FRA1–FRA16 and Equinix FR5. It unifies access to the Internet, IXPs, Cloud providers and private interconnects across the city’s major data center campuses.

With a single physical port, customers can provision multiple services over dedicated VLANs — from IP Transit and IX access to Cloud and DDoS protection. This approach ensures flexibility, transparent billing and seamless scalability without additional cross-connects or hardware changes.
