New colocation facility: F6

Building “F6” is the latest investment of Atman, part of Atman Data Center Warsaw-1 expansion plan. The up-to-date colocation facility, commissioned in September 2021, has 1440 sq. meters of  technical space for servers and guaranteed 3.6 MW of IT power. Data rooms can be freely divided or combined according to customer needs. The building structure is prepared for high density racks. Also, F6 connectivity is excellent (network neutrality, redundant links, dedicated connections to global clouds, e.g. AWS, Google Cloud, Microsoft Azure).
