One Port. Infinite Connections.
MAINPORT unifies access to the Internet, Internet Exchanges and Cloud connectivity across Frankfurt’s leading data centers. A single physical port with dynamic allocation of services and automated billing.
What is MAINPORT?
Traditional colocation means ordering a separate cross-connect for every carrier, exchange, and cloud provider you want to reach. MAINPORT replaces that with a single physical port.
Services are provisioned over dedicated VLANs: Internet, IX access, Cloud, and private interconnects. You add, swap, or scale them without touching hardware, without new cross-connect orders, and with a single unified bill.
What you can run on your port
Choose the services you need and add or scale them at any time without ordering a new cross‑connect.
