Centrum LIM Warsaw: historic interconnection hub

Centrum LIM is a historic interconnection hub in the Marriott hotel tower on Aleje Jerozolimskie in Warsaw. Over the decades it has become one of the most important carrier hotels in Poland. It is a place where telecommunications operators, internet providers and content networks meet to exchange traffic and set up direct connections.

Why Centrum LIM matters

The facility's importance comes from its history and the accumulation of network presence. Once many operators settle in a single building, others want to join to be closer to their partners. This is how a carrier hotel forms: a facility with high interconnection density, where reaching dozens of networks comes down to a cross-connect inside the building, without the costlier and slower route across the public internet.

• One of the first and most recognizable network hubs in Poland.
• A concentration of Polish and international operators and transit providers.
• Direct low-latency cross-connects between racks within the facility.
• Proximity to peering platforms and traffic exchange points present in Warsaw.

Role in the Polish internet

For Polish networks, Centrum LIM is a natural meeting point. Regional operators, internet providers and hosting companies use a presence in this facility to shorten traffic paths to domestic and international partners. Low latency and a wide choice of connectivity providers mean that many routes between Polish networks pass through this very hub.

AS202520 has presence in Centrum LIM, which allows peering, transit and cross-connects to be delivered directly in this historic hub. Operators seeking a short, predictable path to our network in Warsaw get access to AS202520 in one of the best-connected facilities in the country, and onward to other partners present in the building.
