The Coolhousing data center network is not limited only by datacenter itself on Vinohradska, but extends outside of the buildings as well and offers the possibility of direct connections with other Czech and Slovak data centers. Among the Czech ones belong THP Vinohrady, DC CEColo (better known as Sitel) and Nagano data center. Slovakia is represented by the datacenter of the Slovak Technical University. Coolhousing has launched another direct link with the datacenter TTC Teleport on Tiskařska in Prague.
The Coolhousing data center uses these links not only to provide its services to customers, but also to provide customer service outside of datacenter. It is possible to implement backup data circuits with a capacity of up to 1Gbps with all datacenters and optical links with some of them.
Backup ethernet circuit with TTC Teleport was implemented in the first stage, however the next, second stage, is already planned with the expansion of the optical link.
